Add in in-line vlan editing and Bulk vlan editing (#3350)

* Fixes #3341 - Added in-line vlan editing
* Fixes #2160 - Added bulk vlan editing

Inconsequential behaviour changes:

* APISelect can now take "full=True" to return a non-brief set
* Select2 will no group by "group & site, group, site, global" if full=True is set in APISelect
