Fix for frozen strings #12

Closed fcoury closed 12 years ago

fcoury commented 12 years ago

Fixes the problem when adding colors to frozen strings:

1.8.7 :006 > x="a"
 => "a" 
1.8.7 :007 > x.color(:yellow)
 => "\e[33ma\e[0m" 
1.8.7 :009 > x.freeze
 => "a" 
1.8.7 :010 > x.color(:yellow)
TypeError: can't modify frozen string

That looks great, thanks. I'll merge it and release new gem tomorrow.
