Allow bargains in bazaars, ranging from 60% to 95%.

The value of created items is also increased by a fair bit.

I also changed species MR as in the last post of FR 1787813: all Elves get 4, Ogre Mage 5, and Demigods also 4.

Someone (Darshan?) will probably want to twiddle with the numbers, at least for the bazaars, so for now, I'll put off committing this into 0.3.
