Various fixes

Hi,

The next pull requests are based on these fixes.

Sincerely,

Cherry-picked:

• "Fixed display of private collections."
• "Returned only public items."
• "Fixed item type for cdwalite."
• "Fixed token when there is no limit."

Merged separately:

• "Get the true earliest date stamp."

The "URL of repository" stuff is covered in its own PR, and that leaves only "Typo" unaccounted for, which I'm rejecting as not being a typo.
