Build 14: New code for injecting keystrokes

[Freddie]

My apologies for the long delay since the last build.

This new build has a lot of new code in it, but most of it is invisible. Or should be invisible. You may see new bugs in things that used to work.

(How much new code? 43 new files and 66 changed files.)

There are two new features.

1. The code for injecting keystrokes was totally rewritten. It uses a new technique that I never tried in HotkeyNet. Hopefully, if this works:

-- All broadcasted characters will get shifted (capitalized) correctly.

-- The code is very fast (it's done without thread changes).

-- Quick bar icons change appearance correctly if they are bound to [modifier:] macros.

-- It's done purely with the normal operating system API (no hooking or hackery).

-- It works no matter if WoW is remote, local, foreground, or background.

2. The WoW button now displays icons and info for WoWs that are either running on the computer or are configured to be launched by Mojo. In this build, this stuff is only eye candy. It doesn't yet do anything. However you should be able to add icons for instances of WoW that you want to run, and the program should save that info and redisplay it when it restarts.
