1. Show a "bouncing ball" Progress bar when importing from morrowind.ini.
2. Removed dialog that asks for content list name when import game files from morrowind.ini. Instead, name is time stamp.
3. Removed commented out code.
4. Additional bugfix. No longer create a empty content list when OpenMW.cfg has no content files.
