Umherirrender 2cc29f25a0 Add missing documentation to class properties
Add doc-typehints to class properties found by the PropertyDocumentation
sniff to improve the documentation and to remove the exclusion of the
sniff.
The activated sniff avoids that new code is missing doc-typehints or
real-typehints.

Adding a @var type to RSSData->items triggers a SecurityCheck-XSS issue by phan, but all is dealing with wikitext when building the items, so that looks like a false positive
