initial work to support geodash

Document Fixes:

* twitter#1498
* twitter#1555

Grunt Fixes:

* twitter#1465

Improvements:

* show all suggestions when query is empty string
* `dataType` option for `prefetch` and `remote` to support `xml` based sources, such as WMS GetCapabilities.  Used with `transform` function to convert to typeahead compatible json.

Changes:

* Runs `trie` search on results from remote and prefetch, instead of just displaying all results.
* passes url to transform function, so it can be used in search index if needed.
