Apply Leonard's patch for fixing the colors:
The colors were broken again.
* isprint for some reason returned true when the given byte is higher than 255.
The char cast of the byte was then printed which resulted in odd characters
popping up. Black appeared as ^@ which is NULL in caret notation.
* After that, the colors were all messed up because the RLINE enum didn't take
in account the color swapping.
So instead of messing up the enum order/number I went for a new "range-like"
method.
* After fixing all of that, I noticed the Interface::render_colorline had a
broken loop since the VS2010 commits.
This made the lines not print entierely and messed up the colors etc.
