Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Improved the historical discharge calculation. The calculation now creates new HistoricalWQKms (new subclass of WQKms). Those WQKms are used to create new facets from (new) type 'HistoricalDischargeCurveFacet'. The chart generator is improved to support those facets.
