Goodbye Weather, Hello Search Frame

Removes the "Apps" WDN Resource (included weather and directory search) and expands the search tool to support auto-submitting queries to the updated search application that supports iframe (cross-domain) querying.

Integration note: The new search application relies on a template code bug fix that is included in this pull, however, it will not pick up the fix until it is deployed. So the search frame will fail to load until this is deployed to the CDN.
