#36 Remove linux compilation instructions - code is win api specific

[noa body]

I noticed a number of "doesn't build on linux" tickets in the past. While I could overcome some issues. (remove xsrc/q_shared strcasecmp defines), eventually we end up at client/cl_main.c trying to define HINSTANCE which is winAPI specific.

No reason to retool the code into platform specific nodes, just call the project winAPI specific.
