Bunch of fixes, and major refactorization. (Again)

VinewatchX will no longer lock its sound files.
Refactored Streamer and StreamerUtils, and removed a lot of useless functions.
Streamer list on the options form refreshed when names are added or removed.
Removed Refresh button from options form.
Disabled the TopMost property of the main and option forms.
Made all dialogs modal.

Unfortunately, the diffs for Streamer and StreamerUtils are totally unreadable.  Better to just compare the files side by side.
