(minor) moved jQuery.TemplatedWidget template related fields into options

the template options have been fields in the prototype before. It makes kind of sense
to make them available in the options though. An issue with having 'templateShortCuts'
as a field was that inheritance would not be possible with the jQuery Widget system
since only options will get a true copy by $.widget while other objects will be
modified on the base prototype. Our workaround for this only worked for one level of
inheritance (doing the copy manually in the prototype's constructor, can't define the
constructor of the new prototype created by jQuery.widget() though).
