Export folders in existing Blacklight formats

[acozine]

Mirrors existing Blacklight functionality for bookmarks. Export functionality will be for a single folder only - no export of multiple folders in a specified order. The five export formats are:

• Cite (text-based citation format)
• SMS
• Email
• EndNote
• Refworks

Take a look at the following blacklight pull request projectblacklight/blacklight#991 to see if incorporating it might make our work easier.

Per @jcoyne this will be included in Blacklight 5.8 release:
https://github.com/projectblacklight/blacklight/pull/998/files
... which would allow us to use the document_actions method.

If we use that feature, we'll have to update the gemspec to require blacklight 5.8 or higher.

Currently the export to endnote appears to work, but it's actually downloading all the bookmarks. We need to restrict it just to the folder. Refworks is likely behaving the same way.

Blacklight export to RefWorks works from demo.projectblakclight.org - click Export to RefWorks and log in, and the bookmarks get imported. The RefWorks log says:
Import Date: 11/24/2014 11:58:22 AM
Vendor: Blacklight
Import Filter: Direct Export
Export a folder from folders.curationexperts.com triggers "Import Failed" for now.

RefWorks export does not work. Reopening.

Partially fixed by https://github.com/curationexperts/blacklight_folders/pull/87/files - exporting generates a log file but items do not get imported. Refworks documentation here may be helpful: http://www.refworks.com/directexport.htm.

Basic functionality met by 9c69a0c. Further issues will be reported separately.
