Added a tool strip host for the tracking bar, allowing it to be embedded inside a status bar; fixed a bug in the progress reporter form that would prevent AsyncAbort() from actually being called when the user clicked on the cancel button; AsyncProgressBar no longer changes the style of the progress bar, this is now up to the user; ProgressReporterForm now switches ProgressBar between Marquee and Blocks styles on its own; various formatting enhancements
