Grade Hider for The Crag geliştiren: mas

Finds elements on the page that display the grade of a route, and either hides them, or converts them to a 'Vx' grade. The mouseover action of a topo has been removed, but you can still click on a route to highlight it. Routes that you have logged any activity for will have their grade shown as usual. Grades that are listed in descriptions of routes are not hidden.

Grade colour bands (V-scale and Ewbank):
Green = VB- ... VB+ & 1 ... 12
Yellow = V0- ... V0+ & 13 ... 18
Orange = V1 ... V4 & 19 ... 24
Red = V5 .... V10 & 25 ... 32
Purple = V11 ... V17 & 33 ... 39
