validate_colors prevents use of colors for custom levels

[pmaccamp]

Hi kristianmandrup,

In base.rb the colorable levels are restricted to
valid_levels - [:debug, :info, :warn, :error, :fatal]
Which leads to an assertion failure if you try to color a custom level.

I was wondering if there was a reason for this.

Apart from that, thanks for the awesome lib with the exact functionality I needed.

No reason that it should only support these levels. Would be nice with a config single and ton or classbwherebyou couldbset a color and block to for text content for each level IMO. Please tweak as you seebfit ;)

Thanks for the quick reply, I'll see if I can get around to this. Cheers
