* Added 'cacheSessions' flag

* Added a cacheSessions update call to import_file_dict() in fpdb_import.py
* Added updateSessionsCache() method to Hands
* Added storeSessionsCache() to Database --- WORK IN PROGRESS and set to pass
TO DOs
- add sessions queries to SQL
- complete storeSessionsCache() so it works like we've discussed (save for adding sessionId to HP)
- add SessionsCache keys
- add SessionsCache to the default table creation and deletion methods in Database.py
- update storeSessionsCache() and all the relevant db & sql code so it writes a sessionId to HP
