We now use ints, and hopefully this means we don't have as much obvious
stuff in the binaries!
```
$ # Before:
$ strings metsrv.x86.dll | grep core_ | wc -l
46
$ # After:
$ strings metsrv.x86.dll | grep core_ | wc -l
0
```
Big win, and it's even bigger for the likes of stdapi.
Had to fix a bunch of other stuff along the way, including a subtle
issue with the Powershell Meterp bindings.
DCSync functionality is exposed, and from this it is possible to enumerate all users in the domain and dump each user's hash one by one. This code has a few extension functions built into the runner, and also has some baked-in powershell functions that are available in every powershell runner session in the host.
I've also added a powershell version of the build command that lets us generate the source to the powershell assembly wiring from PSH as well as Python.
