1. Variable delta-time flag is now determined by the program, it cannot be set in settings.ini.
2. -min CL argument implemented.
3. tick module now loads only when not running in minimal mode
4. Enchanced the status report.
5. -fe CL argument implemented.
6. -t has split into -tu (time universe) and -tr (time real).
7. Confirmed that continuation of updates is possible when the standard saving scheme is in effect (to the original or a copy).
8. Implemented the continuation of separate save file save scheme unis via the -cnt flag.
9. Implemented the -se flag to save the simulation when it's over.
10. General bugfixes.

Note: I accidentally ran Graviton on unis/solar_system.json with the -se flag and corrupted the data (it saved after 1 real second). However, I had a constant delta-time, and was able to reverse time to get back at 0. There are still imprecisions, around ~1% for velocities which I've checked. Therefore, the dataset will need to be reconstructed.
