Ignore Aptana .project files

Opened Sandbox project in Aptana. Apanta created a .project file that
should only remain on my local pc (contains aptana settings). Right
clicked the change in 'Github for Mac' and clicked 'Ignore'. This added
".project" to the .gitignore file so git will now ignore this file in
the future. So, gitignore needs to be commited/synced.
