Title: NEW: Image->captcha color parameters

Hi,
The built-in captcha generator works really well and fits graphically with most pages. Yet there are a few situations where one might need to customize the captcha colors in order to fit specific page colors.

This pull request adds 2 color parameters to the function call : one for background color, one for text color. Also it allows picking random colors out of an array.
