Add recent photos to subimssion form

[topher1kenobe]

When I go to upload new photos after a week or two, I look in my photos folder, and I can't remember which was the last one I uploaded. I'd love to see the one or two most recent on the upload page.

In 13978:

Photo Directory: Add styles for grid of user's recent submissions on submit page.

See #7600.

In 13980:

Photo Directory, Uploads: Output a grid of the 6 latest submissions by the user on the upload page.

Props topher1kenobe, coffee2code.
Fixes #7600.

FYI @coffee2code Template_Tags\get_photo_as_grid_item() wasn't committed in [13980] and doesn't appear to exist.

Reverting [13980] for now.

In 13983:

Photo Directory, Uploads: Revert [13980].

See #7600.

In 13985:

Photo Directory, Uploads: Output a grid of the 6 latest submissions by the user on the upload page.

Re-committed now that Template_Tags\get_photo_as_grid_item() has also been committed.

Props topher1kenobe, coffee2code.
Fixes #7600.

@dd32: Thanks for the catch and the revert. I've added the missing function in [13984] and re-committed the fix to this request.
