In off-list discussion, Steve mentioned that kdevelop / kate highlighting recognizes "FIXME", but not "FIX-ME", which has been the Audacity convention. This commit changes Audacity code to use the "FIXME" convention (though I've never known it as convention and MSVC doesn't recognize it).

Also, minor change in WaveTrack.cpp in the effort on bug 641. Should have no functional difference.
