[fixed] Irr1.6: Joysticks created with no ID on OSX

[DavidJE13]

CIrrDeviceMacOSX.mm: line 1303-1315
returnInfo is never given a Joystick number. This results in semi-random numbers assigned to joysticks (usually 0, but sometimes other values). This is not the case in the Windows implementation.

to fix, add u32 jindex = 0u; to the top of the activateJoysticks function, and returnInfo.Joystick = jindex; jindex ++; anywhere near line 1308.

(maybe this is considered a hack but it does the job)

I'll note that adding returnInfo.Joystick = info.Joystick; will not fix this because the info.Joystick property is only set later.

(all line numbers based on the release I'm using (1.6), not the SVN)

Thanks, I have changed it in the 1.7 release branch in svn.
