Added logic to reset Random.state in ColorSettings to avoid polutting…

[lordofduct]

ColorSettings has logic that resets the global rng state with a seed of 0. This results in RNG behaving deterministically the same when in the editor.

Fixed by caching the current state of Random and then setting it back after filling the outlines2D array.

Considering the logic as is will always fill outlines2D array with the same values. If this is the intended behavior then it could be refactored to just have a static definition of what should be in outlines2D.

Looks like you mixed up the indentation style, that section uses tabs instead of spaces. Looks like a good change to me otherwise

My IDE does 4-space tabs which look identical to regular tabs in editor. Seems github's font doesn't equal space 4-space and tabs (possibly for python-like languages?). Didn't notice until pull request submitted.
