Aim for native Win32 compatibility

Created by: Zapotek

2 things prevent this right now:

• fork() -- in RPC::Server::Dispatcher, RPC::Server::Instance, process helpers and Browser.
  • The fork() calls can be replaced by spawn()[1] by passing the necessary arguments as environmental variables to a script.
• sys/proctable -- in RPC::Server::Dispatcher and UI::Output to show resource usage when debugging.
  • Thankfully, sys/proctable supports Windows so I just need to encapsulate it in an Arachni class which presents the same interface for all platforms.
