`-setSelectionColor:` woes about rscolorpicker HOT 2 CLOSED

/ping @dblapps

I'm working on adding unit tests to the project so these issues are caught much sooner.

It looks like one solution is to add this to the bottom of RSGetComponentsForColor:

    components[0] /= components[3];
    components[1] /= components[3];
    components[2] /= components[3];

However, @unixpickle and I are looking into a cleaner solution, possibly switching the CGBitmapInfo flag.

The 2 main color spaces on iOS are greyscale and RGB, and so now we're using the helpers for those. That should fix most of the rounding and accuracy issues, including the alpha issues in this issue.
