Rework on the Equipment tab to make it look more Modern.

Note that this is a WIP and it does break functionality
- ie, not possible to add Equipments, but this will be
fixed in the next commit. Removed add / edit / remove
buttons, only a single '+' icon appears on the widget
now. the edit / delete will be done in place.
