Create areas tool should use appropriate cursor

[xeen]

Create areas (default shortcut: x) uses the "select cursor" which is misleading. I attached a better one that at least gives a hint that "create area" is active (it doesn't look too good though).

Create Area Cursor Icon

Here's a "patch":

Image should be copied to /images/cursor/extrude.png

In
/src/org/openstreetmap/josm/actions/mapmode/ExtrudeAction.java
change line 78 from

getCursor("normal", "selection", Cursor.DEFAULT_CURSOR));

to

getCursor("normal", "extrude", Cursor.DEFAULT_CURSOR));

Fixed in r1158.
