Adding refresh event and making TileManager listen for it

When calling redraw(true) on a HTTPRequest layer, mergeNewParams is used to
add a url parameter with a random value. For layer types that do not use
params in the getURL function, the url does not change and the TileManager
will provide tiles from the cache. To make sure that tiles are fetched from
the server, they need to be removed from the cache first.
Clip singleTile image to maxExtent
Override getImageSize function to take clipped images into account

singleTile layers may have clipped images to not exceed the maxExtent.
Whitespace fixes
Use correct getImageSize API

Without the bounds argument, getImageSize would fail in singleTile mode.
Updating tests and adding a test to make sure that clipping works
Changed documentation of OpenLayers.Bounds.toBBOX from Significant Figures to Decimal Places as this is what the method actually does.
