 ### Bug Fixes

 * The P2 DistanceConstraint method signature has changed. Updated Phaser so maxForce is now passed as object (fix #788)
 * Moved the this._reversed flag outside of the property loop in Tween (as per tween.js issue 115)
 * Emitter.makeParticles updated to use Array.isArray() check on the key/frame values, so non-string objects can be passed in (thanks @AnderbergE, fix #786)
+* Tilemap.createFromObjects will now force the creation of the property again even if it doesn't exist (regression fix from 2.0.4)
