Updated `glast` alias to use `--decorate` option.

- Adds colored, branch information.
Refactored `gamendh` alias to use the shorter `--no-edit` option.

- The results are still the same.
Updated .gitconfig to allow `git status` to show all untracked files.

- By default, git status, only shows new directories but not the
  contents within. This not only shows the new directory but also all
  contents within for easier readability.
