py-MechanicalSoup: updated to 0.10.0

Version 0.10

Main changes:
Added StatefulBrowser.refresh() to reload the current page with the same request.
StatefulBrowser.follow_link, StatefulBrowser.submit_selected() and the new \ 
StatefulBrowser.download_link now sets the Referer: HTTP header to the page from \ 
which the link is followed.
Added method StatefulBrowser.download_link, which will download the contents of \ 
a link to a file without changing the state of the browser.
The selector argument of Browser.select_form can now be a bs4.element.Tag in \ 
addition to a CSS selector.
Browser.submit and StatefulBrowser.submit_selected accept a larger number of \ 
keyword arguments. Arguments are forwarded to requests.Session.request.

Internal changes:
StatefulBrowser.choose_submit will now ignore input elements that are missing a \ 
name-attribute instead of raising a KeyError.
Private methods Browser._build_request and Browser._prepare_request have been \ 
replaced by a single method Browser._request.
