Add new policy to reset the jam time when the lineup clock ends.  Useful when counting down with the lineup clock, but not using the lineup-starts-jam or lineup-starts-timeout policies.
Overlay: update status bar fading logic to try not to queue more fades if currently in fade-out, just use the correct new string before fade-in.  This should avoid cases of "Stand By" popping up if there are a few milliseconds of no clocks running in between jam ending and lineup starting (or possibly other situations).
overlay: update version to wftda_overlay6
TABIFY: change spaces to tabs in all default/Default* files.  whitespace change only.
TABIFY: change spaces to tabs in model/* files.  Whitespace change only.
TABIFY: change spaces to tabs in top-level java files.  whitespace change only.
Add interface TeamModel.removeAlternateNameModels() and implementation, to remove all alternate names from team.  Call from team reset() method.
Update LineupClockResetsJamTime policy: fix (big) bug by calling resetTime() instead of just reset(), which was resetting the entire clock instead of just the time; and add a call to changeNumber(1) to increment the jam number, since when the jam starts it won't increment the jam number because the time was reset.
Update version to -wftda_overlay7
