Add Hammer and Other dev tools for source 1/2 games support for linux.
Title says all I want to say.

Though a bit more context, I feel like this has been neglected and yes its nice to see players are getting alot of support from Valve, I want the ability to also make maps on Counterstrike 2 or Team fortress 2. But they either don't work or very unstable under wine.

Please add this and support devs who like to make maps or skins.
