RCM error screen stuck at "PRESS BUTTON TO RESET"

[AndrejValand]

Was playing today a bit with SmartEVSE and there is a small issue with RCM error display. But the issue is only cosmeticall with an easy improvement.

When RCM error is detected a massage is shown that toggles between "RESIDUAL FAULT CURRENT DETECTED" and "PRESS BUTTON TO RESET". No error is displayed over CLI.

When the user presses the button while "PRESS BUTTON TO RESET" massage is displayed, the next time the RCM error is detected there will be "PRESS BUTTON TO RESET" massage displayed and not "RESIDUAL FAULT CURRENT DETECTED" if the detected fault is present for a long period of time.

I made two modifications that improve the RCM trip situation:

GLCD.c

EVSE.c
