Geany forcefully saves project session

[drws]

Geany currently constantly updates .geany project files with no option to choose in which state to save the session (and consequently also have an ability for project-wise presets/defaults). This is leading to issues such as #2304 and #2863.

This is a feature request for additional global option under Preferences > General > Miscellaneous > Projects so one can disable session autosaving and also add a manual option to do so, probably something along the lines of File > Save Project.

Also: Another option in the category Use project-based session files disables using .geany files altogether and is not helpful in the case.

Based on comments from #2863, the previous behaviour can be restored by the files.save_config_on_file_change setting, so this issue is now solved.
