Slightly adapted testBuildProjectPath:
External storage directory doesn't necessarily have to be "/mnt/sdcard/"
UtilFileTest.testFileSize: Fixed false failure with German locale
UtilFile.getSizeAsString returns a locale-aware String (as it should),
but the test compared it to a hardcoded dot, which can fail (for
instance when testing with a German locale which uses a comma).
Also made assert messages slightly more descriptive.
testBuildProjectPath: Use Constants.DEFAULT_ROOT instead of hardcoded
path.

Fixed Issue #118

The Nullpointer occured when the test silently failed and was executed
again due the @FlakyTest annotation. Since the Sprite was a member and
only initialized once, the already running StartScript from the first
try was still running in the background, still calling getScript() in
the LoopEndBrick, which returned null, because all Scripts had been
removed via removeAllScripts() and replaced with a new one, which did
not contain the LoopEndBrick anymore.

Fixed NullPointerException in ForeverBrickTest
Removed warnings from ABS

* One deprecation warning with @SuppressWarnings
* Two unused variables. These remain unused even in 4.2.0, see
https://github.com/JakeWharton/ActionBarSherlock/blob/master/library/src/com/actionbarsherlock/internal/widget/IcsLinearLayout.java#L208

This is so we have a workspace without warnings, since these are not
even our warnings.
