little error in gmoccapy signal names in 2.8 documentation

[hansu]

Only a few little errors in
http://linuxcnc.org/docs/2.8/html/gui/gmoccapy.html#_velocities_and_overrides

The names of the signals

gmoccapy.rapid.rapid_override.counts
gmoccapy.rapid.rapid_override.count-enable 
gmoccapy.rapid.rapid_override.direct-value 
gmoccapy.rapid.rapid_override.analog-enable 

should be

gmoccapy.rapid.rapid-override.counts
gmoccapy.rapid.rapid-override.count-enable 
gmoccapy.rapid.rapid-override.direct-value 
gmoccapy.rapid.rapid-override.analog-enable

0cd671c should fix it
