Use cordova 3.7.0 as experimental

Add new commands for easier checking of the supported framework versions and changing it in the project. The commands are mobileframework print (default one) and mobileframework set. Use the new server API and FrameworkVersion in order to show which versions are experimental.
Should be merged after https://github.com/Icenium/Ice/pull/2586
