Patch for the Setup. Remove android dependency. Add version Options.

This adds a few tweaks to the setup:

* Adds the ability to select version of libgdx 1.0.0+, as well as choose to be put onto the nightlies.
* Removes dependency on Android when you dont have the project selected, no local.properties file is generated, nor will the project check if the sdk location is valid, in fact it disables the field to provide some better feedback.
* Puts box2dlights onto the 2-SNAPSHOT until its released.
* Remove duplicate dependency of x86 natives in the android backend.
* Some visual tweaks like cursors in the text fields
