Support Counter-Strike 2 with CSSharp plugin

With the release of CS2, support for the SourceMod plugin ended, as it is not yet compatible.

CS2 is currently using the CSSharp mod to implement resources on CS2 servers.

I believe that a plugin made in CSSharp for CS2 and synchronizing with Tebex would be perfect at this moment.
