+ Changed protocol to 0.3 because we now accept both -foo and foo

as argument introducers.  in 0.4-pre10, these were changed
   from foo to -foo and this broke many clients.  This change
   should fix that and be backward/forward compatible.
 + Added a noop function to the protocol.  This is useful for writing
   shell script clients of LCDproc.
 + Changed the shared sock_send_string function to NOT send the
   ending NUL ('\0') byte with the string.  This was confusing
   in Perl clients which saw NUL's as the first character of
   each reply.  WARNING: The LCDPROC client depended on this
   behavior, your client may too.  Use the newline instead.
   See the code in clients/lcdproc/main.c (look for "switch(buf[i])")
   to see one way to handle this.  This should allow new clients
   to connect to old servers and vice-versa.
 + Messed with include structure in .c files.  It should no longer
   be necessary to specify ../.. to get to shared code headers.
   Also, since we are using automake, the global config.h can be
   found with just #include "config.h" as it's location is included
   in a -I to the compilers.  As a result "make distcheck" now works.
