Cleanup of English translations and readability in the lhc_web folder 

Final cleanup of all files in the lhc_web folder.  English translations for spelling and readability were done. Renamed the userjoinged.tpl.php to userjoined.tpl.php as this was referenced in the syncadmin, and adminchat this way. Cleaned up the readability of some of the README files and  the CHANGELOG. .
