Themeable Axis Colours

It is now possible (as of r.52026) to customise the axis colours as part of your theme. The main benefit is that now you can tweak these colours so that they are more visible than the old hardcoded ones (a bit of an annoyance of mine with the old colours used). For example:

 Default colours - Note how badly the dark blue tends to fade into the background.

A "softer" set - These are all a bit more visible (and are in fact closer to some of the ones I've seen in other software)

Likewise, you can adjust for darker themes (ZBrush theme used here)...

Or even swap the colour of the "up" axis (if you must :P)
