I recently upgraded my Marlin to V1.1.x and decided to publish my fix to make marlin compile properly when #define board megatronics 2 in combination with #define reprapworld keypad v1.1. It was previously described in the comments of a closed pull request. MarlinFirmware#472. All the buttons on the keypad are now operational.
* [New Feature] I2C position encoder support

There was quite a lot to translate this time. I'm not absolutely confident with the whole UBL stuff and it's a PITA to translate. I don't use any kind of levelling myself as i just have a perfectly level cast aluminium plate as bed.
So maybe someone who really uses it might take a closer look at it after it's merged.
* Remove requirement for LCD when UBL is used.
* fix previous oversights
* further refinement - error messages for P2 & P4
* require R on G26 when not using LCD; default to all points
