Merge pull request #8 from HSWebteam/js_backbone_model_validation

Js backbone model validation
Reworked loading. You can now use $this->ultraform->load('name_form');
to load a json file in the /forms directory of application.
Added templates directory.
Ultraform now validates, repopulates, etc. only for text and password
fields atm.
Changed 'validation' in JSON data files to 'rules'.
Also added 'placeholder' support.
