Added libraries, added ActionBar (support) to MainActivity and updated UT.

Libraries added (app): android-support-v4, android-support-v7-appcompat, android-support-v7-gridlayout.
Libraries added (tests): mockito-1.9.5 (with dependancies: dexmaker, dexmaker-mockito).

Please note that dexmaker used with mockito had to be patched due to unresolved issue occuring on Android 4.3 devices which made running tests impossible, for patch notes please see JIRA.
Introduced Eclipse support for MyGuide and MyGuideTests projects.
