Update 1.8.60 - City Naming, Achievements, Player Name & Bugfixes

Latest Update:

City Naming: functionality to name and rename settlements. Comes with happiness bonus.
Achievements: "Challenger" and "Responder" achievements added. They will be given when an election is held, respectively while voting on an election. Loosely based on http://steamcommunity.com/app/338810/discussions/0/1489992713702634015/
Player Name: for single player games, instead of "Player", the player name can name be selected during game setup!
Clan-ONLY Games: there is now an option to prevent "Non-Clan Players" to join a game (via game setup). That allows both (a) player created games and (b) general events to be limited to clans only for e.g. the clan's championship.
Translations: latest translations added - Thanks :-D
Translations: updated glyphs for rendering added (mostly Chinese & Japanese).
Spelling: misc. fixes (English).
Admin/Moderator: map rejections allow to write a rejection message too now.
Login & Passwords: improved error output for wrong or missing passwords as well as email recovery.
Backend System: updated backend libGDX to 1.9.8.
Bugfix Variable Cache: pillaging, enlarging or sieges would not always properly reset the cached variables, so pressing the UNDO could display results different from actual.
Bugfix Censor: wasn't always properly detecting words that need censoring.
Bugfix Crashes: showing the join-game panel (while it wasn't created yet).
Bugfix Crashes: placing nature while no nature is selected in editor.
Bugfix Crashes: while checking if there are still unviewed events during event display.
Bugfix Crashes: while holding festival and and next turn just started to be loaded.
Bugfix Crashes: while building settlemens and the structure selected was 'null' (cause?).
Bugfix Crashes: when device vibration (Android/iOS) crashed due to insufficient permissions.
Bugfix Crashes: when latest room information was 'null' (ignoring missing data now).
