unified_inventory/internal.lua
Vanessa Dannenberg ebd1d1f245 Improve consistency of inventory (and alike) imagery 
In a number of places, background[] is misused to place the
inventory backdrop images.  Where appropriate, image[] is used
instead, so that "ui_form_bg.png" actually serves as the one
and only true background image.

In so doing, I was able to remake the bag inventory images,
making them only big as is actually needed to hold 1, 2, or 3
rows of inventory slots.

This, in turn, allows a standardized main inventory image to
occupy the lower part of the window, which allows for
consistent inventory image positioning and sizing from one
page to another.

I also removed ui_misc_form.png.  Nothing in UI uses it, and
any external mods that used it can just use the standard
inventory and its background.

Lastly, I reduced the background image to 512x384 px.  It was
unnecessarily large before, considering it has no real detail.

The larger inventory images are all 512px wide, and multiples
of 64px in height.  Before, they were oddly sized.
