- Annotations were using ' to quote text, sanitizing ' -> " inside
the text. It would be better to quote with " and sanitize " -> '
because ' is more common in the text (e.g. "Doesn't work") than ".
- Added support for the "g" modifier to the substitution command,
that replace every occurrence of "from" with "to", in the task
description and any annotations.
- Added support for "annotate" command to annotate existing tasks.
- Bumped file format to version 3, due to the annotations.
- Added unit tests to verify that annotations work.
- Changed 'description' column everywhere to include annotations.
- Added 'description_only' column to exclude the annotations.
- Fixed bug in Table.cpp that calculated the width of multi-line
columns by using the cell length, instead of the length of the
longest individual line.
- Updated documentation with new feature.
- Updated documentation with new column.
- Enhanced t.t unit tests to cover format 43
- Now sanitizes output by replacing ' with " in descriptions.
- Added 'recur' attribute to exported output.
- Removed recurring, deleted and complete tasks from the export.
