Title: When bool value is converted to string, string should be lowercase

This pull request is to fix defect [MAGN-3420 No consistent notation of true / false](http://adsk-oss.myjetbrains.com/youtrack/issue/MAGN-3420#).

The problem is because to ``ToString()`` in .Net which converts ``true`` to ``"True"`` and ``false`` to ``"False"``. There are three cases that we may display string value:
1. Watch window
2. Preview window
3. Default value in library view

So the fix is to change the string to lowercase if the type is boolean.
