New DataView Rendering Type

[EitanBlumin]

Type 1: DataTable Grid (same as today) Type 2: AngularJS Template

The AngularJS (AJS) template will work like this:

• There should be a folder for html partial templates containing AJS-compatible HTML.
• It should be possible to write or upload your own templates.
• The API endpoint should be configurable somehow (because one endpoint should return data in DataTable format, and another endpoint should return data in a custom JSON format). Possibly make it dependent on whether a Source stored procedure was chosen (table as source: use DataTable, procedure as source: use AJS template).
• The template loading should be done using the jQuery.load() function.

The DataTable Grid should probably also be implemented as a partial template file (thus the implementation should be agnostic about the actual web framework in use), and then the user would simply set a single "Layout" combo-box when configuring a DataView.

More detailed implementation design TBD
