add context option

[Sysix]

hey guys,

very nice plugin :) thanks for it.
I have a little problem: If I use the plugin in a container with overflow:hidden the minicolors-container is isolated.

Maybe add a Option like Bootstrap "context" so we can add this on the body-tag or somewhere else.

We have a similar use-case where a modal is generated within a frame and and then displayed in top.document. The events of the color picker listen to document, which is the frame. We could bypass this by changing the event selector to $([document, top.document]), but I'm not sure if this change has some side-effects.
