Player inventory - add an alternative to the context menui

It is only possible to equip and sell weapons by opening the context menu (right click on a row), but this may never be clear to the user.

We should add the functionality to some other controls in order to let the player know that they can manipulate their inventory.

Maybe add "dot menus" to the end of the row? Like so "Great Axe ..." where clicking the "..." will open the context menu.
