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.

These attributes can be any combination of A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE. These constants are defined in <curses.h> and can be combined with the bitwise-OR operator (|). The current attributes of a window are applied to all chtypes that are written into the window with waddch(). Attributes are a property of the chtype, and move with the character through any scrolling or insert/delete operations. attrset() sets the current attributes of the given window to attrs. attroff() turns off the named attributes without affecting any other attributes; attron() turns them on. color_set() sets the window color to the value of color_pair. standout() is the same as attron(A_STANDOUT). standend() is the same as attrset(A_NORMAL); that is, it turns off all attributes. Return Value: All functions return OK on success and ERR on error.
