Allow wearing clothing with OVERSIZE flag with footwear

[Night-Pryanik]

We don't have any footwear with BELTED flag (how is this possible anyway?) and also it will allow wearing regular or emergency blanket, for example, on top of footwear, as was discussed in http://smf.cataclysmdda.com/index.php?topic=12375.0.

Needs not to allow wearing XL boots on top of regular ones.

Oh, I also overlooked for ankle holster and ankle sheath for BELTED footwear, but they have OVERSIZE flag too, so it's ok, I suppose.
Nevertheless, it seems that XL boots is only one type of actual footwear with OVERSIZE. What should I do with this? Add explicit check for these boots?

[Night-Pryanik]

Or maybe add a check for allowing wearing OVERSIZE boots only with volume, say, more than 20?

[Coolthulhu]

No id hardcoding or volume check, that's always a bad idea.

What kind of slot do blankets have? Outer? Is there anything in outer layer that shouldn't be allowed?

[Night-Pryanik]

Yeah, outer. At first I think of it too, but there are anbc suit, hazmat suit, wolf suit, dinosaur suit and some others that I think wouldn't be good with footwear.

[Coolthulhu]

But those aren't OVERSIZE. Anything OVERSIZE+OUTER that doesn't fit over boots?

[Night-Pryanik]

No, I think there's nothing OVERSIZE+OUTER that doesn't fit over boots.

[Night-Pryanik]

Done, I think.
