[/trunk] Changeset 63 by mikael
* Add commands.[ch] files, to deal with command lines.
Move sendmessage() to commands.c
* Update Makefile accordingly.
* Create a scr_WriteMessage() function, layer between UI and the
scr_WriteIncomingMessage() / scr_WriteOutgoingMessage().
(The last one is a new function)
