Improvements to git push/pull handling

Modified script to:
 - Push to remote repo when task-git.sh push is called
 - Pull from remote repo when task-git.sh pull is called
 - Only push to remote repo automatically:
   - If a remote repo exists
   - The task command modifies the task database
   - The --no-push arguement is not passed on the cli
