Fix some incorrect and missing variables

Add headings for each app in the .env in the form of:

#
# APPNAME
#

Fix indenting

Remove extra spaces to pass linting

Move `APPNAME` != `LAST_APPNAME` test to avoid issues with global variables.

Remove extra spaces to pass linting again.

Add an extra line after the "Global settings", so there's a blank line before the first application variable comment.

Add `# APPNAME` and `# APPNAME (User Defined)` headings to .env file.

Change logic to files into arrays and search the arrays instead of reading line by line.

Remove whitespace on blank line

Use `inArray "element" "array"` to check if an element is in an array (fixes "deluge" matching "delugevpn").

Clear `APP_LABEL_LIST` array when a new app is iterated to the `.env` file.

Fix shellcheck errors.

Fix some shellcheck warnings.

Fix more shellcheck warnings.

Fix shell check warning for `'ls`

Fix `shfmt` errors

Fix `shfmt` error

Fix index variable when unsetting element of an array.

Removes `appvars_migrate.sh` and`appvars_migrate_all.sh`.
Migration is done in `appvars_create.sh` if it sees existing variables to be migrated.  Tries to handle not migrating from variables such as `<APPNAME>_PORT_####`, `<APPNAME>_RESTART``, etc.

Fix linting errors.

Check to be sure the the potentially migrated variable name isn't an existing label for the app, instead of using a hardcoded list of exclusions.

Fix linting error

Use an associative array for default variable values.

APP_VAR_VALUE["VARIABLE"]="default value"

Change naming of variables used in script a bit.

Remove whitespace on blank line.

Add missing quotes around variable

Change to updating the `.env` file to after creating variables, to be sure they are sorted correctly.

Add some comments to `appvars_create.sh`

Rename `APP_MIGRATE_VAR` to `APP_VAR_MIGRATE`.
Change a set of two if statements to use `&&`.
Add `debug` lines to check variable values.

Fix linting errors

Make `env_set` create the variable if it doesn't already exist.

No need to add `VAR=` before adding a new variable.  It is now handled by `env_set`.

Add debugging lines

Add a couple more debugging lines

A partial fix to having multiple instances of a variable in the `.env`.  Previously, it would concatenate the values, so that

```
VAR='one'
VAR='two'
```

becomes

'''
VAR='one two'
```

This partially fixes it by only finding the first line in `env_set`, and only finding the last line in `env_get`.  The full fix will be to be sure the `.env` file isn't sorted beforehand, so that the last entry in the file will be the value used.

Fix error message

Change array searches to use `" VALUE " =~ " $(ARRAY[*]} "`
Use explicit `if`
Change an un-needed `continue` to an `if/else`
Remove some now un-needed debugging lines.

Fix array searches to `" ${ARRAY[*]} " =~ " VALUE "

Remove extra space

Search arrays using `" ${ARRAY[@]} " == *" VALUE "*`

Break adding environment sections into a routine.

Fix linting errors

Fix linting errors

Make `ENABLED_LINES` local to block needing it (temporary array).

Improve some comments.

Add comments

Move initialization of `APP_LABEL_LIST` array to before for loop.  It will get reset to empty before each pass of the for loop.

Add a couple more comments.

Remove white space

Add/update comments

Commenting

Re-order variable definitions to make it a bit clearer.  Add and move comments.

Do all processing in `env_update` internally in arrays, no temp files.

Output the array to the new `.;env` file at the end.

Fix linting

No need to compact array after removing items.

Reduce duplicated "Built In" and "User Defined" section output to a loop for builtin/user user defined.

Shorten a variable name.

Fix unbound variable

More consistent variable naming.

Minor comment changes

No need to keep track of index positions of lines added to sections.  Duplicates have already been handled by the associative array, the only duplicates would be from the variables added from the `.env.example` file.

Minor fix to comment... it's adding to a "section", not necessarily the "built in" section.

Replace all references to `mapfile` with `readarray`.  They are the exact same command, but `readarray` seems clearer on what it does.

Ignore whitespace before and after variable when getting and setting variables, to allow `   VAR   ='value'`

Change `env_set` to a simple "Delete variable in file" and "Add variable to file".

Fix variable output in `fatal` command.

Ignore error when deleting a variable (the `.env` file may not exist).

Remove unused variable.

Remove whitespace

Simplify `grep/sed` commands to a single `sed` command to get all variable lines minus whitespace.

Comment out `debug` line
