squish ugly regression bug

• SetSubtraction() was broken by commit 361a09f (i.e. right after v109)
• Was panicking when you try to delete items from searchlists...

hotfixes for bad scansion data formatting in DB

• highlighting scansion in v.1.0.10 exposes a need for a quantityfixer to patch some problems in the DB data as currently formatted

happy new year

• add option to sort vocab lists by headword count
• add option to include scansion info in vocab lists
• some ad hoc patching of odd html in dictionary entries [until HipparchiaBuilder fixes them]

misc minor bugfixes

• fix N words after logic bug
• findendpointsfromlocus() can now do both cicero 4:8:18 and cicero 10:24
• don't panic if .Scan() returns nothing
• formatparsingdata() needed better sorting and deduplication

move to pgx v5

• move from pgx v4 to pgx v5

minor bugfixes and code cleanups

the title says it all... users will only really notice the 'delunate' fixes, if they happen to have that option enabled

fixes to "not near" searches

squished some logic bugs

enable user authentication

a feature that almost nobody will use: require username/password pairs to access search, browse, text, and lexical paths

the default configuration bypasses all of this: every session can do everything

this is only of interest when not serving from 127.0.0.1

minor bugfix and under the hood changes

• arrival order searchlist add/delete bug fixed
• fix for multi-line span formatting
• enable RtWebsocket() to handle multiple simultaneous clients

bugfixes for withinxwords searching

several significant bugfixes are in here for withinxwords searches and there are search cap bugfixes as well; definitely worth upgrading from 102...
