World.wrap will take a game object and if its x/y coordinates fall outside of the world bounds it will be repositioned on the opposite side, for a wrap-around effect.

* Key.reset has a new `hard` parameter which controls the severity of the reset. A soft reset doesn't remove any callbacks or event listeners.
* InputManager.resetLocked - If the Input Manager has been reset locked then all calls made to InputManager.reset, such as from a State change, are ignored.
* Group.resetCursor will reset the Group cursor back to the start of the group, or to the given index value.
* World.wrap will take a game object and if its x/y coordinates fall outside of the world bounds it will be repositioned on the opposite side, for a wrap-around effect.
### Bug Fixes
* The main Timer loop could incorrectly remove TimeEvent if a new one was added specifically during an event callback (thanks @garyyeap, fix #710)
* The main Timer loop could incorrectly remove a TimerEvent if a new one was added specifically during an event callback (thanks @garyyeap, fix #710)
* Fixed the use of the destroy parameter in Group.removeAll and related functions (thanks @AnderbergE, fix #717)
* P2.World.convertTilemap now correctly checks the collides parameter of the tiles as it converts them.
* Animation.destroy didn't correctly clear the onStart, onLoop and onComplete signals.
