Direct Editing of Catalog Items and Prefixes in Content Mode

Ability to have Edit button on Catalog Items and Prefixes when working in Admin -> Content Mode.

On click it will trigger direct editing of that specific item in pop-up or modal window and on save will return to the previous page.

[B]Places & Cases where Edit button can be used:[/B]

1. Item Details page (ie. Product, Link, Article or any other Prefix details page)

2. List of Items (ie. list of Categories, Products, Promo Block or any other Prefixes)

[B]Requirements:[/B]

Since this "Edit" button will be returned/printed by a new Tag

1. We should be able to use the tag within any DefineElement block (for lists)

2. Edit button should work if it happens to be within another form.

3. Add special "class" (ie. edit-item-button) name to this new Edit button element on the Front-end. We might change the look and feel of this Edit button to make it different from Edit Content and Edit Phrase buttons.

4. Ability to replace "Section Properties" button (top right corner) when viewing item detail page (pass "item_prefix" to m_include tag of default_design.des.tpl)
