Update PrevalueEditor to use DataTypes instead of Views
Update editor to work with DataTypes instead of Views

* Add helper methods for getting DataType info (ie, prevalues, property editor alias)
* Add static mapping file of PropertyEditorAlias -> View, as can't seem to find a way to expose this from Umbraco (for now)
* Load the view's config from the DataType's prevalues
Send over a PropertyEditor's DefaultPreValues when building the property view

* Add static mappings for DefaultPreValues to config file (for now - should be able to pull them out)
* Merge in the DefaultPreValues to the Prevalues when building the config
Avoid having the fieldset default to error when added
