Added a few missed vallebox methods back into macoslib from the following classes: NSRunningApplication, NSProcessInfo, NSMutableDictionary, NSString.
Added the sensible ‘else’ to an ‘if’ statement.

Fixed a typo that erroneously set the NSToolbar's default items to the alloweditems array.
NSToolbar only supported NSControls, added the ability to use both NSControls and Controls, updated the NSToolbar example.
RB 2012 supports an alpha channel directly instead of requiring the use of masks, which is good, but is not supported in RB below 2011.04.The original version of this method seems to merely copy the image into the mask, which is not good for coloured icons.Hopefully the RB version below 2011.04 copied the image mask into the mask, otherwise this needs to be fixed.Unfortunately I can't test this, and i'm not sure how to fix this myself for RB below 2011.04.
Used a more recognisable example control for the toolbar.
In Xojo, NSMenu needs to have a constructor with the signature Constructor() to be placed on a window.
Added NSMenu's setdelegate method to it's constructor.
Corrected reverse title/message in NSAlert extension.
