introduces a few new utility functions in misc.c, one of which is
the bitmap obfuscator from Mines (which has therefore been moved out
of mines.c).

is (a) pretty feeble, and (b) means that although Net seeds transfer
between platforms and still generate the same game, there's a
suspicious discrepancy in the typical seed _generated_ by each
platform.
I have a better RNG kicking around in this code base already, so
I'll just use it. Each midend has its own random_state, which it
passes to new_game_seed() as required. A handy consequence of this
is that initial seed data is now passed to midend_new(), which means
that new platform implementors are unlikely to forget to seed the
RNG because failure to do so causes a compile error!

right from scratch without the slightest reference to any dialog
templates (meaning that we get to figure out the layout and _then_
choose the window size). I'm rather pleased with that. Also
introduced free_cfg(), which is why this checkin touched gtk.c as
well.
