Add Client-Logger

[raging-loon]

We need two loggers: one for the engine, and one for the game/client.

There is an engine logger here: https://github.com/raging-loon/Simula-24/blob/f6359efe9c631e26a84e890dcc9a873206f33a11/simula24/core/log/log.h#L159-L175

And its implementation here:

https://github.com/raging-loon/Simula-24/blob/f6359efe9c631e26a84e890dcc9a873206f33a11/simula24/core/log/log.cpp#L10-L16

We need a new clientLogger and associated macros (CLIENT_INFO, CLIENT_DEBUG, etc).
