- editing a multi geometry will no longer pop-up a Tcl window

- solved issue #292 where a new geometry renamed with many underscores failed to store the name in a saved project
- the name for the saved projects are updated to the current time and not to the time of the app startup
- some PEP8 changes related to comments starting with only one '#' symbol
