add contrib script to remove trailing whitespace from files

This tool removes trailing whitespace from files passed on command line.

Usage:  remove_trailing_space.py [filepath ...]

Limitations:
- makes no backups of modified files
- modifies in place
- does not care what files you pass to it
- assumes it can keep the entire stripped file in memory

Always use only on files that are under version control!
