Dependencies - #410

- Completed support for 'task 1 depends:2,-3' to manipulate the
  dependencies.
- Now supports rc.dependency.reminder to indicate when to nag about
  dependency chain violations, defaulting to on.
- Now supports rc.dependency.confirm to require confirmation before
  fixing dependency chains, defaulting to on.
- New source file dependency.cpp which implements a low-level API for
  determining dependency status, and assorted handlers for task state
  changes.
- Adds blocking tasks to the 'next' report.
- Added more dependency unit tests, changed the wording in a couple of
  them and numbered them for easy reference.

+ Added feature #391, now the 'task color legend' command will show
samples of all the defined colors and color rules from your .taskrc
and theme.
+ Added feature #410, and now task supports dependencies between tasks
with the syntax 'task 1 depends:2' to add a dependency, or 'task 1
depends:-2' to remove a dependency.
+ Added feature #421, and now task can sync data files from two sources
via the 'merge' command.
+ Added feature #423, now custom report filters allow rc overrides.
