Split long line.

Do you want to always enable OBJECT_PRINT and INSPECTOR when enabling lol?

[marklam, 2011/01/19 09:43:22]

Done.  Yes, I want it ti always enable INSPECTOR and OBJECT_PRINT defined
whenever lol is enabled.

Maybe add a warning here if liveobjectlist is on and debuggersupport is off
saying that debuggersupport will be forced on by enabling liveobjectlist - or
maybe that is just a wast of time.

[marklam, 2011/01/19 09:43:22]

Done.
