0.2.198

Added: Download limit for indexers. When the download limit is reached for an indexer it will not be picked for searching. Please note that Hydra
will never prevent downloads from happening even when the download limit is reached. This is to make sure that external tools do not disable Hydra
when a requested download fails. See #247.

Fixed: Some hit limit related bugs.

Fixed: Multiple UI issues, e.g. tooltip placement, header "active section" display, etc.
