milaq 16387a3f50 Rework directory handling
This greatly improves loading times and takes some load off the APIs.

 * Add generic directory class to also hold item count
 * Radiobrowser: Get station count directly from API
 * Optionally show broken stations and their count
 * Remove minimum station bitrate to not filter away some listings
 * Improve code wording
 * Log API requests
