Administration all category view and search

[deweblooper]

On system Administration Category page is hard to manage many categories if employee don´t know whole categories tree, when catalog contains let´s say 1270 categories ordered in 15 main categories and then each other subcategories in 3-4 sublevels.
And it is not possible to search and find any category in tree, just visible on actual level, so it is not useful at all.

This enhancement add new button to header toolbar for jump to other - new view with categories full list - new page "Categories quick list"

and also add to system new controller for displaying extra page with all catalog categories (pagination with numeber of pages viewed is also there), where employee can search and find any category in catalog like charm.
This new page also use buttons for preview selected category from FO, or straight open category editor in BO.
