logmerger 0.7.0

Added

• Support for CSV input files. logmerger looks at the first column of the CSV for the timestamp.
• Table displays and updates while loading data.
• Early detection of end-of-time-range, without reading the remainder of the input file.
• Notification when loading a large log file is complete.
• Bell when pressing N or P without defining a search string using F.
• Timestamps in log files that are marked with "+/-nnnn" or "Z" timezone indicators are converted to local time.
• Changelog links in CHANGELOG.md.

Fixed

• Log lines containing rich-style text tags could raise exceptions in several output modes. Now tag introducers
  in lines are '' escaped before sending to rich or textual.
