Fixing transparency issues in CToolBar.  Adding CToolBar tool tip messages.  Adding support for disabling toolbar buttons.
Instrument toolbar button disabling works.  Fix for issue where instrument name editing doesn't change the instrument name in the instrument list widget.
Fixing shortcut-redirected key events.  The key events should be sent to the focusWidget if it's valid, or the main window [or perhaps the view] if it's not.  Fixing bug causing invalid song number to be used in the Module Properties dialog when a song is added.
Fixing TrackPopupMenu - it was sending the menu action command for TPM_RETURNCMD. Removing superfluous blockSignals calls during window show/hide and dialog initialization. Fixed CButton's window message - included BN_CLICKED even though it's 0. Added EN_SETFOCUS handling in focusInEvent of CEdit but then realized that the handler is hooked to the incorrect dialog element in the original FamiTracker.
Clean up.
