Android: Fix Intent based file chooser and switch to using it by default.
The old dialog based file chooser is still included as a fallback for now.
Only run the color chooser if called on the main thread, this should not be
a problem since almost nothing except expose callbacks run on the main
thread. The intent based file chooser can't choose directories, so for now
operate like normal, but return the path to the chosen file instead of the
file itself.
