Adds change event trigger for ColorPicker if color is updated

If you want to use the color picker to select a color for an element that is currently visible, it might be nice to update the color of the element "live", i.e. each time the user updates the selected color, the element gets the new color. Currently, there is no way to detect when the user has changed the selected color. Now, they can simply listen to the `change` event of the input field.

Added ability to force links to frontend

If you ever create a cronjob and you would like to link to a frontend page (you're not supposed to link to the ACP anyway), you MUST set 'forceFrontend' to true. If you fail, there's some special place in hell for you!
