Added inventory action

[Balferian]

Allow users to see full item info about items from account/character/guild pages. Module used for (inventory / cart / storage / guild storage) items.

Added new acceess configs:

'SeeItemUniqueID' => AccountLevel::LOWGM, // Ability to see item unique ID.

This config shows you the item's unique ID, it's hidden from normal users.

item->inventory: AccountLevel::ANYONE

If user have permission for this action then he will redirected to inventory module else to view module.

It is useful if you want to show/share link to item.
