-												Reworked README and xmlx/entitymap.go. Now includes conversion of named xml entities instead of just numeric ones. Eg: &pi; and &#960; to a unicode character and vice-versa. It also came to my attention that lack of a proper opensource license might put people off of using this package. I therefor added a 1-clause BSD license under which this code now falls.

This removes the support for re-indenting XML, but allows to faithfully
parse / stringify a document. Beautification could be added again later
on if desired.
