Add the ability to display a "waiting" mouse cursor while a new layer is being loaded

[fvanderbiest]

This happens when I check a new layer (specially when singleTile is true, which makes it longer to produce) : the user should be informed that this new layer has been requested and is being loaded.

Basically you need to register two event handlers on every layer: one for 'loadstart' and the other for 'loadend' event. Then you can change the cursor type in the callback functions.

Replying to fredj:

Indeed, that works. Thank's Fred. But should'nt this feature be factorized across projects inside Map Fish? ?

[sypasche]

There could be a helper class in mapfish which would do the registration and event processing. It could then be connected with the Ext progress widgets or could simply setting the mouse cursor.

#82 needs more discussion as whether we can make something in MF or not
