Added system commands ( features: custom argument number, default values, system command builder, ...).
Fixed bug not copying attachment when using copy and send.
This causes problems with group messages as the received date is null
sometimes even though the status is RECEIVED.
The ReceivedMessageProcessor on the client filters out the synced
messages at the moment.
Common
* Replace LocalDateTime with Instant everywhere
Client
* Display message creation date with system time zone in MessageControl
* LocalDB#users now strictly contains Users
* lastSync time stamp in LocalDB (saved per user)
* isOnline parameter in save function (lastSync updated if true)
* lastSync time stamp in LoginCredentials
* No ClientConfig#getLoginCredentials because of missing information,
moved to LoginScene
* Pass LocalDB#lastSync to LoginCredentials in LoginScene
Server
* Explicit lastSync parameter for
PersistenceManager#getPending(Group)Messages
This sends the correct time stamp to the server, however the JPQL
queries have yet to be adjusted.
