Deltabot settings and configuration adjustments.
Use X/Y/Z_MAX_PIN instead of X/Y/Z_MIN_PIN for top endstops on deltabot.
Enable QUICK_HOME for deltabot.
Add realtime delta geometry in Marlin_main.cpp.
Fix typo in MANUAL_HOME_POSITION (plural S missing) and reduce BLOCK_BUFFER_SIZE because 64 wasn't working for some reason.
Merged updates from Marlin_v1.
Fix home_all_axis to make QUICK_HOME work with Repetier-Host which sends G28 X0 Y0 Z0 instead of G28. Thanks to Matt Schoenholz for reporting this issue.
Fix typo (# missing before define).
{X,Y,Z}_{MIN,MAX}_POS are actually in Gcode coordinates.
