Update imapstorage.txt documentation.

Updated the imapstorage.txt documentation to reflect that issues with
c-client versions older than 2007 seem to cause crashing issues that
are not seen with more recent versions. Documentation has been updated
to reflect this.

+If you do not have the University of Washington's IMAP c-client

+source distribution from http://www.washington.edu/imap/ and compile it.
+Asterisk supports the 2007 version of c-client as there appears to be issues
+with older versions which cause Asterisk to crash in certain scenarios. It
+is highly recommended that you utilize a current version of the c-client
+libraries. Additionally, mail\_expunge\_full is enabled in the 2006 and later
+versions.
 
 Note that Asterisk only uses the 'client' portion of the UW IMAP toolkit,
 but building it also builds an IMAP server and various other utilities.
