coloring fix on macos

[staxfur]

I have dicussed with @certik that mixing styles and colors by doing the ansi codes adter each other (like \033[34m\033[1m) we should combine them like \033[1;34m which should create the same output (bold blue) than the first and longer escape code. Besides that this would tighten the menu class rendering, I'm wondering if it also fixes the color issue on macos.

@certik can you confirm that? I have still no macos device on my hand.

I came over this combined syntax while trying out golang a bit. Hope it fixes the issue.
