New vba.py features include:
* get_memory_at
* get_memory_range
* set_memory_at
Also, the "crystal" class has a number of specialty helpers:
* crystal.walk_through_walls
* crystal.get_player_name
* crystal.get_map_name
* crystal.get_xy
* crystal.nstep (which sets memory each step by calling certain
* functions, like walk_through_walls)
* crystal.is_in_battle
* crystal.get_gender
A quirk of the Decompressed class dissociated the orientation from
the output attribute.
The makefile no longer suppresses output since it's still relevant.
Extras:
-function to dump trainer pals
-fix testing leftover in a compression function
-keep load_rom() from getting in the way (relative address breaks extras)
There was an incompatible change to the json module api between py26 and
py27, causing gbz80disasm to not work with py26. The fix is to simply
alias the new loads method to the old read function.
A possibly better plan might be to not support py26 at all.
