Description

This PR fixes issue #776 by properly handling user profiles with more than 50 published projects. It also fixes an off-by-one bug which I still not sure how I didn't catch in the initial implementation (basically it would skip the first project of every user profile)

Testing

Required verification:

• I've verified that there are no regressions in mvn test (there are no new failures or errors).

  • Downloads all relevant content.
  • Downloads content from multiple pages (as necessary or appropriate).
  • Saves content at reasonable file names (e.g. page titles or content IDs) to help easily browse downloaded content.
• I've verified that this change did not break existing functionality (especially in the Ripper I modified).

Optional but recommended:

• I've added a unit test to cover my change.
