Implemented New Permission: Bypass moderation queue when creating items

Starting with Showcase 2.6.0 Beta 1, there is a NEW Showcase User Permission 'Bypass moderation queue when creating items' that replaces the OLD permission 'Create Items Moderated' (as it was confusing to set 2 "create" permissions for some people.

Create Items = The ability to create (nothing less, nothing more).

Bypass moderation queue when creating items = If not set, then newly created items will go into the Moderation Queue for approval. When SET, items will be immediately published and publicly viewable.

NOTE: You will have to SET this (per user group) as part of Post Upgrade steps since its a NEW permission.
