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
```

# but things like Vectors and Colors do since only the parameters to create a
# new Vector or Color are included in the metadata.
