Detect android projects automatically. Set compiler, tags and classpath accordingly
Merge pull request #1 from DonnieWest/AutomaticProjectDetection

Vim Grand can now automatically detect android projects and load on start
Renamed utils.py to sys_helper, and added fileExistsInCwd()
Added project check to GrandSetup
Combined GrandSetup and GrandDetect functionality
Removed GrandDetect command as it had the same functionality as GrandSetup
