fix Jagex's mismatched textures

<Stormy> [crumbled wall texture being updated in textures7.jag] makes most of the places where it was used look inconsistent.
<Logg> yeah, i guess he thought he only needed one crumbled wall :ehehe:
<Logg> and then realized "oops no i need that other crumbled wall"
<Logg> and now sapphire house is mismatched like you said. >_<
<Stormy> first use of that texture was likely Ghost Town.
<Logg> for rsc-c client, make it so that it uses textures7 crumbled wall if you are in the wilderness :ehehe:
<Logg> it's a bug fix
<Stormy> yeah, we can do that.
<Stormy> we could also fix the windows in e.g. Rimmington, which suffered the same issue.

not possible to do this for the entire wilderness because of the western ruins but we could at least fix individual buildings that are mismatched
