improve presentation of log results

Currently, results are very lightly formatted and presented like this:

This can be improved by:

• replace the log priority with a color coded log line
  • use the same colors as existing log colors
• replace plugin names with shortened versions
• make plugin names links to their doc page
• tabulate the data (columns: transaction #, plugin name, log entry)
