html fix
added module aware bubbler, can traverse models which are connected by their module (and not parent field directly)
removed bad debug print :(
rewritten routing and many related code parts
created ModPageRootModule and it is now the entry point for routing
removed Filter, and created similar ViewScope. templates do not see the Model directly any more but see Model, View, Data. Model's
attributes are still accessable directly
created a ViewEngine layer. this layer encapsulates template finding and rendering. View layer rather acts as an actor, its getters
can be called from the template
created ViewEndineMustache and ViewEngineJson
