Do not free reply on error.
Fixed focus not being updated after a window is removed.

Thanks Reiser for picking up on this.
Added config.h to the makefile check target.
IPC socket initialisation is completed. I am assigning FDs to the display and socket and will use select() to process events.
Added the select statement to correctly process input.
Howm and cottage are correctly communicating. Processing of the incoming commands needs to be done, as well as howm sending responses.
IPC now works, although in a VERY limited manner.
Add howm to list of available X sessions (for display managers)

This adds and will install an X session desktop entry file in order to
    list howm as an available X session to display managers that read
    available sessions from /usr/share/xsessions
