New Sound Test plugin

Lets you listen to your game's BGM or sounds without interrupting your
current task! :o)
Hotfixes for Open Last Project, SoundTest

Plugins weren't getting OpenProject event when last project loaded on
startup. Also made SoundTest not stop playing BGM when sound effect
played
Make SoundTest menu items/tools work

It was getting annoying not being able to stop the music. ;-)
Hotfix for SoundTest menu position

Put Sound Test menu before Help menu instead of after
Add icons for Sound Test playback toolbuttons

Icons from the Tango set. Also removed superfluous Sound Test menu
SoundTest polishing, bug fix

Now displays title of playing track in toolbar; also fixed a bug where
playing a sound effect while music is playing would prevent you from
stopping the music
More SoundTest polishing

Added dedicated pause button; separated track display from actual
toolbuttons
Finalize Sound Test plugin (1.0)

All prettied up and bug free.  Now searches for all audio formats
supported by IrrKlang.
Implement TestGame event

Also renamed events to match normal .NET event naming conventions
(events aren't supposed to start with 'On')
Merge pull request #6 from powercommand/master
