Enable users to first create an album, and then add new or existing photos to it.
This reverses the current album-creation flow: create album -> add photos, instead of upload photos -> create album.
On the Galleries page, add a "New Gallery" button -- this should open a Create Gallery page. It should use the same layout as a published gallery, with editable fields for the gallery title and description at the top, and a large box for uploading photos below it.
- Do we show all user photos below, with checkboxes to select photos to add? (Could be troublesome with a lot of photos)
- Or do we rely on the Photos page (with bulk actions) for users adding existing photos?
