"temporary" sketch style from Vector layer does not get applied to OpenLayers.Handler.RegularPolygon

[zanchin]

If a custom "temporary" sketch style is specified in a styleMap that is given to a Vector layer, none of the RegularPolygon sketches use that style. However, the Point handler does the right thing and uses the temporary style during sketching.

Currently (as of SVN 10517), the activate method of OpenLayers.Handler.RegularPolygon drops options.layerOptions that is passed into the constructor. The fix in the patch below makes the RegularPolygon handler work the same as the Point handler in this case.

Namely, it:

1. Doesn't set this.style if a styleMap is specified in layerOptions
2. Passes through layerOptions to the temporary Vector layer in activate()

Same as above, but with APIdocs and declaration for layerOptions

@zanchin: Very nice fix. I can confirm that tests still pass. Can you please follow these instructions and send a CLA? I can commit your fix as soon as you have added a comment to this ticket that the CLA was sent.

appologies for the delay - the ICLA has been mailed (the fax number did not answer).

(In [10645]) Give ReglarPolygon handler a layerOptions config option. p=zanchin, r=me (closes #2755)
