Added bot plugin, it also has almost-functional botnet.
Changed configure.in's functionality so that you could tell what modules you want to build in main irssi binary and it will create automatically the .c files that need to call the module_init()/deinit() functions. Fixed several minor things.. git-svn-id: http://svn.irssi.org/repos/irssi/trunk@230 dbcabf3a-b0e7-0310-adc4-f8d773084564
