[Lazarus] No Mac Hourglass cursor

[Anthony Tekatch]

The Mac cursor cannot be changed to an hourglass, it stays as a pointer.

Tested on:
 Mac OSX 10.6.8 Intel core
 Lazarus 1.4.4
 Carbon
 Using example code /Developer/lazarus/examples/cursors/project1.lpi

Change any of the buttons from their existing cursor definition to
crHourglass and the button only shows a regular pointer.

The crSQLWait cursor shows properly.

Any ideas greatly appreciated!
