rFactor 2 and Java 7 compatible release

New features:

• Support for rFactor 2
• Polished internal code structure to allow for easier bindings to other sims.
• Support for JRE 7
• New DrivingAidsWidget (doesn't do much under rf1)
• New DeviceStatesWidget (speed limiter, ignition, front and rear flaps) (doesn't do much under rf1)
• New StatusFlagsWidget (only green and blue so far because of rf2 API limitations) (doesn't do much under rf1)
• New very simplistic TireLockWidget (under Extras)
• Max Revs and fuel tank size are now used from the Telemetry Info instead of (not available) physics data.
• Fully supports separate core/data folders.

Known shortcomings under rf2:

• Since there is not currently a way to read physics files or the AIW under rf2, a lot of data will be missing like tire temperature limits, pressures, engine and brake lifetime, track map, etc.
• The HUD will not be displayed from the beginning, but after that plugin symbol in the upper left has disappeared. ISI likes it this way.
