Irrelevant - it's an easy fix

Issue description:

In Script main.gd in this project, the constant for the Protocol Name is defined in line 04 thus:
const PROTO_NAME = "ludus"

This is properly used in the code later down, but not in line 73. where instead the content of PROTO_NAME is typed out again. So, Line 73 should read:
host.listen(DEF_PORT, PoolStringArray([PROTO_NAME]), true)
instead of
host.listen(DEF_PORT, PoolStringArray(["ludus"]), true)

The reason why this matters is that when users presume the code to be fine they might just change the constant at the top (which I did) only to find that if you rename it the connections no longer work for apparently no reason.

That is all.
