Plugin Support, Performance Improvements

This update has support for plugins. You can now implement IConsolePlugin from another .NET DLL & load it. This can be achieved by adding the file into the config folder (located at AppData/Roaming/Console/saved) or by using the load_plugin command. The plugins have a lot of functionality, such as hooking user input, hooking setting changes and more.

Improved initial loading speeds by 93%! This was done by loading all the PATH executables in Parallel.
