Rewording and Spacing fix

As per kevingranade's idea, brought item descriptions closer to reality
by saying torches heat the blade, instead of turning into a pillar of
fire, which was a little silly.  Also tweaked descriptions in iuse.cpp
to reflect this.

Big reformatting to recipe.json, so it looks like someone typed it
instead of just smacking the keyboard with their forehead (I can't
believe I actually POSTED that mess!).

Note:  I can't actually compile this to test it right now as I'm working
on my notebook because I'm out of town.  This is pretty much just a text
edit though, so I don't forsee any problems.

PS - I apologize for the previous terrible description of the flame
katana (Rising Sun).  I just hit total writer's block with that and it
was all I could think of.  The new description's a lot better (I hope).
