Fix for #82 and other comparison related issues
Merge branch 'master' into dev
Matched ItemEdit icon to ItemBrowser

data["image"] has {frame} appended to it. This causes an error when the
image is loaded.

Fixes #81 and Fixes #83 until {frame} in the data["image"] can be delt
with properly for animated images.

Changed .scaledToHeight to .scaledToWidth.
Attempt at better image scaling

Still not perfect for weapons because the images have built in
whitespace. Improves it until the {frame} syntax can be parsed I
believe.
