Repetier v1.0.3 DRO display wrong

Problem with Z DRO display on manual screen when not homing axis and doing a G92 to manually set position.

My Z home switch is broken so I can't home Z. Repitier Z DRO shows 0 in red at startup. In order to get around Marlin soft limits I do a "G92 Z100" to allow me room to manually set axis position. After G92 DRO displays Z as -100 in red. I do a G114 to read Marlin DRO's and Z shows 100 correctly. Displayed DRO does not equal machine DRO. Confusing at best.

Suggestions:
1. Do a G114 and update DRO's if user does a manual G92.
2. Add a "get dro" button to manual screen. Safe, no negative implications if user pushes it.
3. Provide a way to manually reset DRO settings (not safe).

First the host shows absolute positions, so G92 should not change coordinates.
Red coordinates means no homing occured so value may be incorrect. This also allows to go below z=0 which is prevented when coordinates are known.
If you are at home and firmware things the same you can send @isathome and host will set itself to origin.
You can use one of the 5 script buttons to add the command to it.
M114 updates the coordinates as well from printer (not G114). Just not sure what it does with G92 gotten so far.
