disabled api_status calls from kicking in on every page
initial oboe.js integration. Added newsubmit and oboe_submit.

path /newsubmit renders ajax-ified newsubmit page. Limitations of
current Discussit code only allow chunked-delivery, making ajax
kinda pointless. Second, helper methods aren't attributes and are
then inaccessible in JS; i.e. site.location is non-existant attr.
newsubmit page now working. better JS structuring and naming.

Still using Oboe but left commented out $.get() as the current use
through rails leaves progressive-load functionality unused.
 - top and all submit blocks load in with AJAX
 - newsubmit loading page now has spinner placeholder
 - cleaner code in static_pages#submit (old submit)
 - moved JS assets for spinner and Oboe into vendor
Changed listing creation to persist common attrs instead of accessors

Formerly listings were created with accessors that returned commonly
used attributes like site-name, discussion-location-url, and score.
Now attributes are coded directly into listing rather than dynamically
added. this allows them to be accessible externally (i.e. in new
submit page with AJAX and presented in JSON API returns).
Changed comment_count attribute to num_comments for all listings.

Now more consistent for accessing comment counts and persisted as
attributes on listing rather than old-style dynamic accessor method.
Added filtering of zero-comment threads to submit page.

Now listed under 3rd section 'filtered-results'.  Collapsed on load
and accordians open on click.
 - currently only filters all-results, not top-results
 - not implemented for API. No filtering applied
Changed score display on submit to show '-' instead of 0 for slashdot
Updated Changelog and Readme. Version bump and feature descripts
Added submit-page filtering for top-results to mirror all-results
