Sprite.loadTexture and Image.loadTexture now no longer call updateTexture if the texture given is a RenderTexture. This fixes issues with RetroFonts in IE11 WebGL as well as other RenderTexture related IE11 problems (phaserjs#1310 phaserjs#1381 phaserjs#1523)

 * P2.Body.clearCollision default values were incorrectly set to `false` if no parameters were provided, even though the docs said they were `true` (thanks @brianbunch #1597)
 * BitmapText.font wouldn't update an internal Pixi property (fontName) causing the text to fail to change font (thanks @starnut #1602)
 * Fixed issue in PIXI.Text where it was using the wrong string for descender text measurements.
