pull request #345 - theme room dimensions

Browse Source 
"When a room is created and passed down to a contents function in
Lua, the width and height properties of that room are computed by
subtracting lx from hx and ly from hy, which means e.g. a room
which is 8 floor squares wide and 5 tall appears to the contents
function as having a width of 7 and height of 4.  This patch fixes
that off-by-one."

I don't understand the details here:  should a room's dimensions
include its boundary walls or just the inner amount?  This change
didn't seem to cause any problems so I've put it in.

Closes #345
