Allow repeater to initialize without a dataSource and no options

[kevinparkerson]

Fixes #1167 by allowing repeater to load if no dataSource has been provided. Also attempts to address issue #1166 by making the repeater still function if bad data or no data is passed back in the dataSource, and provides better defaults for itemization and pagination in the event of poor data scenarios.

Also fixes a random bug I noticed with the deselected event in repeater-list

@kevinparkerson - does this allow for rendering of the column headers prior to data being loaded?

[kevinparkerson]

@mbeard not in this PR, but that is something we could do for a new issue / PR. I think it would be the addition of a "renderColumnHeaders" function to repeater-list

This is working great with repeater-list. When I use repeater thumbnail view as default, I do not get no items found on the repo's index.html page, even though it's specified in the initiation options.

[kevinparkerson]

There was some bad logic from the plugin API translation in the repeater-thumbnail before function that would not render the thumbnail container in certain circumstances, so the noItemsHTML never appeared. Good catch!

Font size needs to be over written if empty. It's currently .1px, so "no items found" is present, but not readable.
