Add GUT (CLI only) and remove gd-plug
Commit GUT directly to the git repo and remove gd-plug as it is no
longer required to install GUT.

Modify GUT to be used by command-line only.

For example:
```
cp test/.gutconfig.ci.json .gutconfig.json
godot --no-window -s addons/gut/gut_cmdln.gd
```

# This class sends input to one or more recievers. The receivers' _input,
# _unhandled_input, and _gui_input are called sending InputEvent* events.
# InputEvents can be sent via the helper methods or a custom made InputEvent
# can be sent via send_event(...)
#
