More slideshow updates.  #1331

- Renamed new slideshow to slideshow.  Unlisted old slideshow from add new widgets list.
- Added edit links to box form.  Made it a little prettier too.  Destination paramter is set to the current page (which is the box form) but if the box form already has its own destination parameter, that's appended to the new destination url as a query string.  This actually works.  I'm surprised too.
- os_get_bundle_alter didn't work because slideshow_image is not listed among os bundles.  Need another way to remove it from node/add and cp/content.  Tried editing the cp/content view to no avail.
- Slideshow is currently bound to the image field's one possible crop dimension.  Haven't investigated how to change it yet.
