Title: Made the Launchable Property tester use the presentation compiler.

This makes the Debug As/Run As menus much faster. It was not uncommon to wait for many
seconds when hovering over those menus. Added a bunch of tests as well.

Fixed #100818, #100082 along the way.

Still need to find a way to disable the JavaLaunchableTester, which causes the same slowdown (trying to find if a file can be Run As Java Application). See [1001178](http://www.assembla.com/spaces/scala-ide/tickets/1001178-disable-javalaunchabletester-on-scala-files)
