3.2.0

Update syntax highlighting for tags, according to the latest klog file format specification:

• Tags can contain dashes, e.g. #tag-with-dashes. (#under_scores had already been allowed before.)
• Tags can have values, e.g. #tag=value
  • Values are delimited by a = from the tag name. You can use them for additional meta-data. Real-life examples: #project=175 or #movie=pulp-fiction
  • Values can be quoted, e.g. #movie="Pulp Fiction" or #movie='Pulp Fiction'
