A component to track skip statistics for foobar2000 audio files.

Features:

• Custom column patterns: %skip_count%, %last_skip%, %latest_skip%, %first_skip%, %oldest_skip%, %skip_times%, %skip_times_raw%, and %skip_times_js%
• Context menu to clear skip counter, latest skip timestamp, oldest skip timestamp, all skip timestamps, and all but the most recent skip timestamps
• Context menu to copy-paste skip statistics to other tracks
• Context menu to write skip statistics to tags and import from tags
• Context menu to export skip statistics to XML
• Settings to modify which actions (next, random, previous, or double-click) count as skips and how long before a skip no longer counts
• Optional grace period after skipping with custom duration and action specific settings
• Timestamp logging, off by default
• Settings for all context menu actions

XML export now only exports oldest/latest timestamps if a skip timestamp exists
Correctly set empty fields when data is not logged for skips
Fixed a 32-bit version specific error with oldest skip not correctly being larger than the largest possible timestamp
Correct JSON formatting of timestamps
