Add "Duplicate to" functionality

[cdsmith-umn]

@Syxton I'm looking at this and trying it out. I like the feature. One thing I noticed is that when you duplicate something, it actually moves the original copy to the "Duplicate to" destination and leaves the new copy in the section where the original was prior to the duplication. Was that intended? It seems counter-intuitive to me. (I had expected the new copy to be in the "Duplicate to" destination, with the original left in the original section.) How do you feel about my changing that behaviour?

[Syxton]

I actually hadn't noticed that..oops. Absolutely needs to change.

[cdsmith-umn]

@Syxton No problem. I'll get it changed.

This has been merged into Mass Actions and is available from the master branch now. Thank you! (Credit given in the README)

I'm getting a 'Target section does not exist' error when I tested this.

[cdsmith-umn]

I'll investigate

I also noticed that the Move to box isn't being populated with sections.

I have the first problem solved. Working on the Move to box

[Syxton]

module.js line 87

    // add to move-to-section
    var section_option      = document.createElement('option');
    section_option.text     = section_text;
    section_option.value    = section_number;
    section_moveto.options[section_moveto.options.length] = section_option;

    // add to duplicate-to-section
    var section_option      = document.createElement('option');
    section_option.text     = section_text;
    section_option.value    = section_number;
    section_dupto.options[section_dupto.options.length] = section_option;

[Syxton]

not exactly sure why I couldn't reuse that variable....

[cdsmith-umn]

Yep. I just found the problem myself. I'll have it up on Github momentarily.

The fix is up on Github now.
