- Added unit test to ensure correct F4 and JSON parse/compose.
- Many files were missing an explicit cmake.h include. Some were not including it at all. Now it's used almost everywhere. (cherry picked from commit 82ae86979c497e6d1d0c6b2b5a55aa379ec82c98)
- Added a non-trivial JSON task to parse.
- The import command now uses the built-in Task::parseJSON method. - Began t3.t.cpp for JSON parsing tests.
