remove libircclient from shared library

* removes libircclient from libzetaglest shared library because the
editor and g3d_viewer also link against libzetaglest. Those 2 binaries
don't need libircclient support

* libircclient is now built directly into only the zetaglest binary

* moved libircclient from source/shared_lib because it's no longer part
of the shared library

* libircclient put in dir "external/" because it is an "external" or
"3rd" party library. The @Supertux project does something similar

external/libircclient/cocoa/Classes/DDInvocationGrabber.m
