ignore <i> tags

[mistergraphx]

Hi,

first thx for this useful tool !! ;-)

i use fixie in a styleGuide tool , and use a lots of tag for styling icons in my markup .Fixie insert random text in these ones. i've modified the source and added a case/break; it's better in my use case : what do you think about this addition ?

maybe we can do better by adding a rule on the class like .icn-xx or .icon-xxx ?
