Re-added Package Control settings to repo.

I removed it before because it has a list of installed packages and
I saw that as being environment specific. But, the reality is that
whenever I move onto a different computer I want that list so I know
what I need to install.

Of course, maybe I should be putting my whole Packages directory in
version control…
Disabled indentation detection and removal of trailing spaces on save.

As I saw before, removal of trailing white spaces on save just dirties
up the commits.

The automatic indentation detection was causing unpredictable and
unwanted results especially with Drupal *.module files.
Added key binding for selecting text between brackets.
