Clarify use of NPBACKUP_KEY_LOCATION and NPBACKUP_KEY_COMMAND?

[rdiaz02]

I think it might be worth to clarify, in the Wiki, under https://github.com/netinvent/npbackup/wiki/Security,-permissions-and-keys#aes-encryption-keys , that the environment variables NPBACKUP_KEY_LOCATION or NPBACKUP_KEY_COMMAND must be given before running NPBackup; in particular, it does not work if we specify them in "Environment variables" in the GUI.

(This might be obvious to many people, but it tripped me a couple of times).

Indeed it sounds pretty obvious to me, but then again I'm probably too used my own software ;)
I've updated the wiki. Please tell me if it makes more sense now.

That is much clearer, thanks a lot!!
I think there is a typo, though: "NPBACKUP_KEY_LOCATION is used to specify thre path to the key file (...)": "thre" I think should be "the".
And, out of abundance of precaution against people who might make the same mistake as myself 😅, maybe a parenthetical note could be added to the sentence "This file can later be used by NPBackup by defining one of the following environment variable in the shell you use to run NPBackup:". Maybe something like (I use italics to indicate the suggestion) "This file can later be used by NPBackup by defining one of the following environment variable in the shell (not as an argument in "Environment variables" in the GUI) you use to run NPBackup:"

Tried to make it more clear again.
English not being my 1st language, I appreciate those improvements.
