Fixed calendar date display bug
Array dereferencing warning
debugged rest of crew editing.  Still an issue with crew display on calendar when a crew member has more than one role, like "(C, T)".  Cell is showing with extra white space on right.  Problem may be related to calendar.css.
more debugging of manage months -- not there yet.
updated roles from Brady's list, added SESSION['mygroup'] variable, cleaned up help index.
cleaned up admin's home page, guest volunteer application
Staged the User Help pagees for Assignment 8, folding in Brady's suggestions.  Removed most of the screenshots and useless help pages, renamed and relinked help screen index with individual help pages.
Fixed menu to be more compact and use session variable
