BOT revision 4 update

We’ve combined the BOT Expert Advisor with the BOT indicator in this latest revision.  Also we’ve ensured that it’s compatible with the new MT4 build release – however there are more expected updates coming from MetaQuotes, so pending that update, more code revisions may be needed.  Members can now download the new revision 4 in the members area.  Please note that a new revision may be released soon.
