Small icon updates for itemstime panel
I made a few revisions after the merge of the itemstime panel:
Because HUD icons are inherited from the default theme, it is unnecessary to add identical icons to the luminos theme. So I removed them to save some space.
There already are icons for the strength and shield powerups, it is redundant to add second versions. However, the quality of the new icons is a lot better than the old ones, so I moved
To match these new powerup icons, I updated the buff and superweapons icons.
I added new icons to the Luma theme.
