bug fix in "dreams, weird and wandering" that would give clearbody to a random teammate as well

i forgot to tweak shadeSkin for balance

added The Best Teacher event. this is a strictly solo wilderness event htat can result in a tough battle.

fixing a bug in the travelling bazaar where the hooks added only lasted for the campaign

added a story: Dreams, Weird and Wandering - this story only triggers if you have completed the weird hook and no longer have the clearbody or parasite buff from it. it puts it back on for the rest of the campaign.

Added a pet ability upgrade for the eyebat: it gives you a low range 1 true damage mini-indignance (same as indignance 1) which you can trade for 2 turns of +2 potency once per combat (the indignance region goes to 0 damage, I couldn't figure out how to get rid of it all together)

but unlike indignance it doesn't break greyplane.

added some protections to ensure the eyebat doesn't end up slapped on top of soem other mods shoulder pet, or that you don't get the option for another eyebat on a second play through

added an option to the barter story to trade a core pet (drauven bird first) for an eyebat pet. (it makes you immune to flanking)

i intend to add an upgrade to the eyebat eventually. currently it will offer no upgrade.

added the story "Barter" - lets a well equiped hero swap a piece for an antique from a passing collector.
