Installer now downloads MSVC redist if required.
Replaced icon with the LOOT one.
BOSS -> LOOT for docs.

Mostly just search/replace, will need to be read over later to make sure
I didn't miss anything.
BOSS -> LOOT for remaining non-code files.
More BOSS -> LOOT

Packaging scripts, masterlist converter and a few missed version number
changes.
Updated copyright tagline in all source files.
Uppercase BOSS->LOOT in source files.

Just search/replace.
Lowercase boss->loot in source files.
More BOSS/LOOT search/replace.
Fixed copyright date and renamed readmes.
Updated readme images.
Corrected default masterlist URLs.
Masterlist updater improvements.

* Removed unnecessary code.
* Updating now update's the local repo's HEAD.
* If updating is disabled, an unedited masterlist's version can still be
obtained.
Only active plugins show inactive master errors.

Fixes issue #123.
Implemented global priority switch.
Renamed translation files, updated template.
Fixed crash due to corrupt plugins.

However, the messages in the catch block never get displayed, and I
can't figure out why. Without the block, LOOT will crash, so it's
definitely catching there...

Also tweaked how validity check messages are attached.
Fixed undefined var.
Some minor refactoring of constants.

Moved message types, languages, and game constants to their respective
classes.
Somehow missed updating version number.
