Added: Poor man's load balancing. For each indexer you can define a number x and for every API call that indexer will be picked with a chance of 1/x. For example with a value of 3 it will on average be picked on every third API call (if it meets all other restrictions).
This should allow to distribute access to indexers with a low API hit limit over a day. It's up to you to find sensible values.

Changed: Rewrote the caps check error handling some more because this causes problems and questions very often. Added a message saying that you can set the IDs manually and which links to the Wiki.

Fixed: Database error when calling --help. See #563.

Fixed: Validation of URL base setting allowed a trailing slash. See #569.
