- fix issue:

    abort() called
    *** Terminating app due to uncaught exception 'NSInvalidArgumentException'
    reason: '*** -blueComponent not defined for the NSColor NSCustomColorSpace Generic RGB colorspace 0.5 0.5 0.5 1; need to first convert colorspace.'
- remove superfluous color conversions; according to NSGradient docs, any needed colorspace conversions of params are automatic
- use [NSColor colorWithAlphaComponent] to force alpha
- change [NSColor colorWithSRGBRed] to [NSColor colorWithDeviceRed] for 10.6 API compatibilty
- [cosmetic] rename parm withEndColor -> endColor
- [leak] release NSGradient
