Integration - "projects" report

- "projects" report converted to 1.8.0.
- Relocated code from task.cpp to recur.cpp to allow unit tests to link
  without includign task.cpp and therefore main.
- Removed obsolete sandbox directory.
- Fixed bug where Config::load deleted the pre-loaded custom reports.
- Fixed bug where Cmd::valid failed to include custom reports properly.
