* Implemented 'ti sync'

The ticgit repository needs to be remote and tracked.
In the original repository do something like:
1) ti  # to create the ticgit branch
2) git push origin ticgit # to push it to remote
3) git branch -D ticgit
4) git checkout --track -b ticgit origin/ticgit
5) git checkout master # in my case is branch I usually work on
6) use ticgit normally and call 'ti sync' when you want to sync with the remote repository

When you colaborate you do something like:
1) git clone git://(...)  # clone the repository you want
2) git checkout --trac -b ticgit origin/ticgit
3) git checkout master # in my case is branch I usually work on
4) use ticgit normally and call 'ti sync' when you want to sync with the remote
repository
