Light Disciple Robes, clothing fixes

This fixes a variety of clothing and tailor issues.

* Can wear pants & skirts all the time. No conflict with robes, which will go over them.

* New Light Disciple Robes item drops from orc wizards very rarely. All stats the same as normal disciple robes, but they have no sleeves.

* All arm color issues fixed. No more Ugly Arm Syndrome after "tepal new look" or after taking off robes.

* Tepal's buying item limit of 100 lifted, as we did to Herbutte. Nobody seems to know that Tepal buys gems and sundries (edibles / food / drink), probably because offering him more than 100 resulted in refusal, and he's on the island, where gems and food items are rare.
