gitk-git: add option to remove indentation on the commit comment

Indentation make us hard to copy-paste the content of commit comment
from gitk to other medium, especially when creating change log.

The "git log --pretty=raw" command does not have option to re-format
the pretty output again, so the only way to remove indentation is
by trimming left space line by line.

This changes add option "Remove indentation on comment" under
"General" option in Preference.  If its checked the comment will
rendered without left space; otherwise it will displayed as usual.
