- Implemented libtool-ltdl. Only shared modules are supported currently
- Several build fixes and cleanups. ircd now builds and runs without any problems
- Added back all files to SVN that are needed to built the daemon
  I really don't want to force other people that want to test the snapshots
  or svn versions to install yyacc, lex, automake, autoconf and libtool...
  No problem having required files in svn
- Removed some automake maintainer stuff which is kinda useless for us
