Real time graph didn't scroll when target api where above 13 and added ability to disable touch gestures

The real time graph didn't scroll when the target sdk version where set to above 13, for instance here: https://github.com/jjoe64/GraphView-Demos/blob/master/AndroidManifest.xml#L7
I also added the ability to disable touch gestures.

I have also added a .gitignore, so it will ignore the different files that is created when you compile the library. You will have to delete these files, since it will not ignore them as they are already present in the library:
* .classpath	
* .project
* .proguard.cfg
