Style Attributes Content Handler

[ggalileo]

This pull request is for a new common content handler that we have developed at Constant Contact.

The Style Attribute Content Handler will remove all unsupported style attribute items from all elements in the supplied content. The set of supported style attribute items is configured in the same manner as other content handler plugins via config in

Aloha.settings.contentHandler.handler.styleattribute.
