[QOL display enhancement] Show reload cost on equip screen slots

[blackadder]

The display of TU costs to move gear from each equipment slot is MUCH appreciated.   My suggestion is to add the reload cost in a similar manner on the left hand/right hand slots when they have a reloadable weapon, possibly as "R: +20TU" so the player can easily calculate the total cost by adding the slot TU cost + reload cost.   Also possibly the Unload cost under the Unload button.
