Title: Fix a graphical bug in Firefox - Should fix #24

The graphical bug in Firefox was caused by the anti-aliasing between the colored border and the transparent one.

You can read more information on this 'issue' on this blog post from Chris Morgan: [CSS's "transparent" may not be transparent, especially on diagonal borders](http://coderwall.com/p/tpmsta)

I resolved the issue by replacing transparent by the user-selected color with an alpha of 0. Transparent is still used for IE8 who do not know rgba().
