caltechlibrary/dibs: Version 0.1.1

* When running in debug mode, loan durations and reloan waits are set to 1 minute. * When _not_ running in debug, loans by staff/library users are not counted in the histories, to avoid skewing the loan statistics. * Currently active loans are shown in bold face in the `/stats` page. * When the refresh poll max is reached during auto-refresh on the `/item` pages, a different message is shown to the user alerting them that they need to manually reload the page in order to see updates. * The `/item` pages should have disabled to the page cache to prevent stale data from being shown to users.
