Switching back to (modified) l4dtoolz

I have modified the l4dtoolz C++ source code and complied it by myself.
The custom maps are not crashing anymore with my l4dtoolz version.
See here if you want to know more:

The main reason for using l4dtoolz again was, that it shows now 10 players in the steam group server list of the game.
But with unmodified l4dtoolz some custom maps were crashing.

Currently the modified new l4dtoolz version is running on alServ2018 and alServ2019.
And left4downtown is switched back to the no-playerslots version.
