Alpha 6 - Battle

What did I done here ?

• Battle

  • Battle Entities : Battle, EngagedArmy, Fight, FightingUnit, BattleLog
  • Attack now trigger Battle when relevant
  • Added the Battle page V0 (no units displayed, battle stats not implemented)
  • Show Attacking Generals animations on Map and Management pages
  • Battle resolution after time (V0 : score each army, the best score wins, losing army is obliterated)
  • Fortification is now functional

• Refactor the logic that load map data (server now send json and js fetch info from it)

  • Removed the mess in Map.twig.html
  • I implemented JsonSerializable on Entities to fetch the info
  • js now directly read the json and can easily get any data

• Other changes / fixes ...

  • Map : Settings color gauges are now more responsive.
  • User page : Relation / Rights buttons now all have tooltips
  • Added various cheats to speed up debug

Before merging :

• Merge all migrations
• Add ArmyContainer dedicated to the Battle & copy army data to those local battle ArmyContainer (so it's not linked to an actual General or City container)
