added radiobuttons to the client_testing page
removing optionCollection and optionModel as they complexify the structure
Merge branch 'master' of https://github.com/HSWebteam/ultraform into client_radiobuttons
some startup checks work again now that we removed optionmodel and optioncollection, validation stopped working
validation now works for radiobutton and checkboxes
changed concat to serialize and concatvalue to serializedvalue
removed debug code
Merge pull request #85 from HSWebteam/client_radiobuttons
