-------------------------------------------------------------------

This patch adds readline support to ZooKeeperMain, plus a bunch of other stuff: auto-completion
of commands and znodes, scrollable history, redo any of the last 10 commands, a prompt that
displays the command count, optional surpression of watch notifications and defaults to localhost:2181
if no -server flag is given on the command line.

Dropped / failed connections still fail fairly ugly, might be an idea to add a 'connect' command
and catch the exceptions. 

This depends on JLine 0.9.94 (available here: http://sourceforge.net/project/showfiles.php?group_id=64033&package_id=61095&release_id=578593),
and the patch includes an update to the buildfile to look for the jar in src/java/lib.

I have another version without readline support that does most of the above stuff without
scrollable history or tab auto-completion - it's not as nice to use as the readline enabled
version.

> ------------------------------------------------------------
> Possible improvements:
> Default host list to localhost:2181 when not given.
> Don't print a ton of debug, it looks like both cli_mt and zkCli.sh does this. Make a
simple ls that lists subnodes one line at a time and a simple cat that lists only the node
content, simple put etc.
> Shell with gnu readline capabilities and tab completion on node names would be a big
improvement of usability during testing and debugging.
