audacity/src/AudacityApp.cpp
Leland Lucius fa99433113 Updated/fixed ProgressDialog for wx3 
This also re-enables the splash screen and recombines the
OnInit() and FinishInits() since I'm pretty sure the progress
dialog was the issue.

I also retested (as much as I could) and cleaned out all of the
little "hacks" the progress dialog gained over the years.  With
the new modal handling of wx3, it seems that things are much better
behaved.

However, it seems that wxGTK (at least) has gained some new focus
probs (to be dealt with later).
