Network upgrade and new reconnection mode:
* users can disconnect or close app without game progress loose now;
* disconnect dialog will show active tables stats and additional options;
* all active tables will be restored on reconnect (tables, tourneys, games, drafts, sideboarding, constructing);
* user must use same server and username on next connection;
* there are few minutes for reconnect until server kick off a disconnected player from all player's tables (concede/loose);
* now you can safety reconnect after IP change (after proxy/vpn/wifi/router restart);
Other improvements and fixes:
* gui: main menu - improved switch panel button, added stats about current tables/panels;
* gui: improved data sync and updates (fixes many use cases with empty battlefield, not started games/drafts/tourneys, not updatable drafts, etc);
* gui: improved stability on game updates (fixes some random errors related to wrong threads);
* server: fixed miss messages about player's disconnection problems for other players in the chat;
* refactor: simplified and improved connection and network related code, deleted outdated code, added docs;
* tests: improved load test to support lands only set for more stable performance/network testing (set TEST_AI_RANDOM_DECK_SETS = PELP and run test_TwoAIPlayGame_Multiple);
I used Intellij IDEA to automatically refactor code to achive 3 goals.
1) get rid of anonymouse classes, and replace the with lamba to get more readeable and clean code (like in TableWaitingDialog).
2) make effectively final variables actually final to avoid inadvertent changes on it in further releases and keep objects as immutable, as possible.
3) Get rid of unused imports (most of the changes) in whole project classes.
