[videoinfoscanner] scan the entire subtree of path passed to scanner.

- fixes new files not getting picked up when more than 1 level down.
- fixes hashing never being used when scanning a single directory.
Respect parent path decision when cleaning paths.

When cleaning the video library and a source containing TV shows was unavailable,
choosing to keep it only kept the source root, while subdirectories were
removed.
The result was that TV shows "disappeared".

This is fixed by checking if there's a decision for the parent path when
cleaning the path table.

[CEC] fixed: re-enable CEC logging by default after fba4e391197b92d2e49c936a3a13fe785014d31c.
It can still be disabled for people who don't want to see CEC logging, but it'll now be enabled again by default when debugging is enabled, like it was in Gotham.
