1) I wrote a function that formats output from scripts in a consistent way. Although we haven't really come to a concensus on how it should look yet, it's easy to change when we do.
2) New script: smb-enum-groups.nse. Enumerate the local groups on a system and their membership.
* Updated the way authentication works on smb -- it's significantly cleaner now
* smb-enum-shares.nse gives significantly better output now (it checks if shares are writable)
* Added a script that checks if smbv2 is enabled on a server
* Added smb-psexec, a script for executing commands on a remote Windows server. I also included some default scripts, a compiled .exe to run everything, and a ton of documentation (in the form of NSEDoc)
* Added 'override' parameters to some of the functions in smb.lua, which lets the programmer override any field in an outgoing SMB packet without modifying smb.lua.
* Lots of random code cleanups in the smb-* scripts/libraries
