Title: multipart form: configurable url_quote method + recalc size cache of 

This pull request deals with two issues while using a multipart form:

* as described in https://github.com/benoitc/restkit/issues/82 the url_quote results in problems with some rest apis. This fix makes it possible to control the behavior.
* after inserting some additional boundary item into a form after 'get_size' was called once there was no api way to recalculate the size of the form. I introduced a keyword argument to do so.
