Waveforms are now more useful:

 - Closes #12
 - Refactored a bunch of stuff
 - Fixed some bugs with the volume slider and fades
 - Fixed a bug where if no fade out was specified the sound cue wouldn't respect it's duration field
 - Fixed some threading issues
 - WaveFormRenderer now exclusively runs on the main thread
 - Improved mouse capturing
 - The waveform now responds to the volume slider
 - Added a playback marker to the waveform
 - Added In and Out point draggable markers to the waveform to make it easier to set the start time and duration of clips
 - Lots of bugfixes (and new bugs!) to the WaveForm control
 - Added transport controls to the waveform window
