updated forms in portlet hub demo to use enctype=multipart/form-data encoding
minor change to use / as regular expression delimiter
Added code to Portlet Hub to manipulate browser history. As first step,
generate a render url for new page state and add it to browser history
so that state is retained through page refresh and to allow bookmarking.
Completed session history prototype. Adapted portlets to store control
stats as parameters so that they are propery set when navigating through
the history.
Improved code structure in portlet hub impl by having 'updateWhenIdle'
function return a promise. Added code for graceful degradation when the
browser does not support html5 session management.
minor change in portletHubImpl to use addEventListener for popstate event
Worked on adding support for 'application/x-www-form-urlencoded' forms.
Completed support for forms with enctype =
'application/x-www-form-urlencoded'. The hub now supports this encoding as
well as 'multipart/form-data encoding.
