- Addressed bug #804 by allowing rc.hyphenate to control whether hyphens are
inserted when long lines are broken. This may help prevent xterm from
mis-parsing URLs in task annotations, when wrapped (thanks to Yann Davin).
- Added unit tests.
- Added feature #800, adding a new command 'columns' that lists all the columns
available for custom reports, and includes their formatting options (thanks
to T. Charles Yun).
- Refactored column objects to contain a ::validate method, for the
validation of incoming data.
- Context.columns is now a vector of one of each column object,
indexed by attribute name, for validation purposes.
- The ColumnDepends object was failing to map uuid --> id and so
rendered no data for the blocked report.
- Code used the term 'blocked' when it should have used the term
'blocking'.
