Small changes & fixes

[threethan]

I fixed a few more things since the last pull request. Mainly:

1. I extended the xbox button prompts to a few more places that are used only in the equipment/materia menus
2. I removed a few more unused or unnoticeable pixels to fix some more nasty issues with linear texture filtering
3. I upscaled UI_glows, which are used when the DMW goes full screen. (Previously they were very pixelated)
4. I fixed the pixelation on the weird blob in Combat UI 1.png. This is used as the background behind enemy names/libra info

I'm unsure why there is a conflict, since I was the last one to update Combat UI 1.png anyways. The only change is fixing the Libra/Enemy Name background blob
