host chooser - added filter feature

Allows for the list of hosts to be domain or partition specific, if
desired.
integrations update

Added GA universal, which is host specific and leverages the new host
chooser feature.
Some updates to plugin ID's for some of the older integrations so they
conform to the new naming standard.
Support for a 'custom' integration with a few generic inputs. These will
appear in 'other'.
store search - disable sorting

This was left from earlier testing.
product editor - start of new sku-finder feature

For product that have a lot of inventory-able options, there was
potential for browser lockup.  This feature will detect a high number of
sku's for a given product and instead of listing them, will present a
chooser (attributes tab, variations, competition and buy.com were
impacted by this).
Works.  needs styling.
updates

the getProductInventory function was updated to accept an object instead
of a pid.
