CoreInto 0.52.0

Public licensing answers for a product's own website, such as intopanel.com: licence plans and prices, published release notes, and a licence check by server IP. Both are off by default; switch them on under General Settings > Store ("Publish licence plans and releases for your website" and "Public licence check by server IP"). They never show a client's name, email, licence key, domain or amounts paid, and each visitor is rate limited. Includes 0.51.1 to 0.51.3. No database changes.
