Armature: Fix/Change bone axes display.

Now the axes are displayed correctly at the tip of the bone and with the
axes names.

I've made some modifications though:
- Axes are colored. (should not be in object mode but that's TODO)
- Axes ends are not flat arrows anymore. Replaced with a small diamond.
- Axes names are now scale by their respective axes instead of being
  affected by other axes.
- Changed axes names "font" to be a bit more sexy.
