CollectHelper.lua - add buttons to help with collections
## Description
This plugin adds the button(s) to the "Selected Images" module:
1) Return to Previous Collection
2) Collect on image's Folder
3) Collect on image's Color Label(s)
4) Collect on All (AND)
It also adds 3 preferences to the lua options dialog box which allow the user to activate/deactivate the 3 "Collect on" buttons.
Button Behavior:
1) Return to Previous Collection - Will reset the collect parameters to the previously active settings
2) Collect on image's Folder - Will change the collect parameters to be "Folder" with a value of the selected image's folder location
3) Collect on image's Color Label(s) - Will change the collect parameter to be "Color" with a value of the selected images color labels, will apply multiple parameters with AND logic if multiple exist
4) Collect on All (AND) - Will collect on all parameters activated by the preferences dialog, as such this button is redundant if you only have one of the two other options enabled
