[BUGFIX] Change event listening in jquery.minicolors and disable grunt copy

A bug in the jquery.minicolors library prevents the generation in an frame
and proper representation in the global document, as the library listens
to events in the frame (`document`) only, but the elements placed are in
`top.document`. Due to this, the event listening is changed and the grunt
copy command for this file is disabled to prevent overriding the library.
