This change adds a lot of flexibility to working with tile layers: Sources where the server projection or tile grid do not matter can now be constructed without specifying a projection or tile grid. The tileUrlFunction/imageUrlFunction now also creates updated URLs when the params of the layer change, so things like mergeNewParams in ol2 will be possible. A nice side effect of this whole change is that there is no more duplicated code between tiled and single image WMS layers. While I was at it, I also fixed a WMS 1.1.1 axis order issue and incorrect STYLES params (STYLES=& instead of STYLES&).
