Option to store Aegisub's project garbage separately from the script file about aegisub

[CoffeeFlux]

I think you underestimate how useful the extradata is. The default save should really retain it imo, though I agree that some of the project settings should be stored elsewhere on the machine and am still thinking on how best to implement that. Dropping the info entirely by default isn't acceptable, as it's pretty useful despite the name.

I have an idea for a workaround for both the first issue and the third.

Currently, commit c41e97c already removed the Aeigsub Project Garbage when exporting the file using File > Export Subtitles... but the default Save still has them.

Instead of Save saving the file as .ass with the garbage, it could save it in the same way as the export function. Then, under export could be an option to export the file as an .ass, but named an Aegisub Project file or something along those lines.

Or there could be another Save as... option similar to this:

where the project version would include the project garbage, both still sharing the same extension.

With the name, "Aegisub Project Garbage", it seems like this was an unrealized feature for the original team.

To give a bit of an update on this issue, it's worth noting that the git collaboration issue can also be alleviated using a custom merge driver such as assdiff3.
