Uset .tmgit instead of .dotfiles as git dir about linux-time-machine.sh HOT 2 CLOSED

Changed .dotfiles to .tmgit as base dir for git dir.

If you're updating this code on a current project, you must:

1. Before updating, disable tmgit.sh calls on crontab
2. Update tmgit.sh and functions.sh files
3. Go to your project directory (cd my_versioned_dir), then run:
   mv .dotfiles .tmgit
4. Reenable your cron OR run it manually first, but exactly as you put on your cron:
   eval $(crontab -l | grep -E -v '^#|push-remote' | grep /MY_VERSIONED_DIR | awk '{print $6}')

from linux-time-machine.sh.

Code merged into dev branch. Will try to solve issue #14 before update do master and then generate a 0.6 release
