* Remove unsued 'flags' parameter in methods for storing savegames.
* Refactor static constructors when reading objects from savegames so that the ctors are named "newFromParcel", to differentiate them from "readFromParcel".
* Do not read "tilewidth" and "tileheight" from <map>, always assume 32.
* Do not read "tilewidth" and "tileheight" from <tileset>, always assume 32.
* Do not read "width" and "height" from <layer>, always assume same size as map.
* Do not read "width" and "height" from <objectgroup>, always assume same size as map.
* Do not read <image> inside <tileset>. Always assume tileset name is same as image resource name from ResourceLoader.
* Outdoors is a better name for this, because that's what we actually mean by it. Outside is ambiguous in this context. Outside is what it's called in Swedish :)
Renames "isActive" on spawnareas to "isSpawning" - so that a spawn area can be non-spawning but still have monsters left in it.
Adds new scripteffect types:
* "spawnAll" = sets spawn area to spawning and spawns all monsters
* "removeSpawnArea" = sets a spawn area to non-spawning and removes all mobs
* "deactivateSpawnArea" = sets a spawn area to non-spawning
* "activateMapChangeArea" = sets a mapchange area to non-active
* "deactivateMapChangeArea" = sets a mapchange area to non-active (so that it does not teleport the player)
Adds new property "active" to spawn- and mapchange areas in tmx files, that determines whether the areas are active when starting a new game.
* Stores the "isActive" boolean in savegames for map objects and spawn areas
* Adds functions in MapController to activate and deactivate MapObject areas
* Adds functions in MonsterSpawnController to activate and deactivate MonsterSpawnAreas
* When a spawn area is deactivated, all monsters should be removed, since the spawn area is considered to be non-existant.
* Adds boolean "isActiveForNewGame" to map objects and spawn areas, that specify what "isActive" should be set to when starting a game. (Initially, all of these are true)
* This commit does not add any way to actually activate or deactive areas. That can come as a later commit (possibly using script effects to do that).
