Alpha Release 0.6.0

Changes from 0.5.0:

C++ Changes:

• Added EventListeners, which listen for events; both SDL and custom, and triggers user-defined callbacks.
• The existing EventManager code has been replaced with EventListeners.
• Disabled vsync and set a default framerate of 60FPS.

Lua Changes:

• Removed random in favour of Lua's math.random.
• Added new options to window to:
  • Get/set window position
  • Enable/disable user resizing of the window.
  • Minimising/maximising the window.
  • Capturing the mouse whilst in the window.
  • Enabling/disabling vsync.

Other Changes:

• This project now uses a vcpkg manifest to handle package versioning. This is to ensure packages like spdlog use a version of fmt that it can be successfully built with.
• Moved tutorials into the projects/tutorial folder.
• Added new tutorial 05 for event handling.
• Moved tutorial 09a to tutorial 06.
