MIRTH-2738: Added warning in the message browser when user attempts a text search. The user can choose not to show the warning anymore, in which case a flag is stored in the user preferences. Also refactored "Quick Search" everywhere to "Text Search".
Maps and errors can now be encrypted and message export/import/archiving.

MapContent and ErrorContent now contain an encrypted boolean. MapContent holds a content object that is either a map or the serialized and encrypted string representation of the map.
