Added color prefs for Sketcher create geometry ops

[jcb]

Hi:

Working on light background I had some difficulty viewing sketcher geometry creation operations. The default colors for these is hard coded at present. The cursor crosshair is set to white and the editCurve color is SoMaterial diffuse color default of very light gray (80% white)

I added a minor enhancement with two additional color preferences for the Sketcher: crosshair and editCurve.

Some screenshots to demonstrate:

the default geometry while creating appearance:

the new preferences in default state (which was chosen to be current hardcoded values):

altered sketcher colors preferences:

how the alternate color cursor crosshair appears:

how the geometry being created appears with alternate color choices:

Users with idiosyncratic color preferences might find this useful.

Thanks man, for me it's very useful because i prefere a white background too.
But where i can find the PR or your code?

It's in master already git commit c770ce7a343072dd2df

The black cursor works only for sketcher geometrie tools, not for sketcher constraints tools.
