updating FB module

changing to v4 of php SDK
figuring things out

apparently I don't know how to work git
actually adding new FB submodule

got it.. maybe..
Limit to #Boatsnap members

Update to limit to #Boatsnap FB group members only
fixed variable declaration

$inBS = false;
needed to be set higher
minor text update

hid "you can't snap with us" if no user object is available
cleaned foreach syntax

Not as up-to-date with PHP.  Used a copy/paste syntax for the foreach
loop to process Group IDs.  Removed an unneccessary segment.
