Remove all empty option elements

Cleaned up the XML files by removing all <option>

Rename files to ”.icls”

The color scheme files now include ”Language Defaults”
settings so the file names are changed to use the new ”.icls” suffix.
The ”buildjar.sh” and ”buildjar.bat” scripts are updated to
copy the files to versions named ”.xml” to maintain backwards
compatibility with IntelliJ IDEA versions prior to 12.1.
