updating bitcoin to 0.9.2.1
fixing whitespace
plan9port:
	- Update to 20140306
	- Fixed libXt dependency.  The compiler could not find X11/IntrinsicP.h, even though it is available through the nix store.  I think there must be some issue with the 9c compiler being used and not obeying the CFLAGS that nix is supposed to pass.  There are probably other dependencies I'm missing, but 9c found in my /usr/include.
plan9port: builder.sh called install script twice, meaning a redundant recompile.
Merge branch 'master' of ssh://github.com/vvanpo/nixpkgs into plan9port
