Session saving

[Yagich]

closes #67
Hey! A while ago I made the above issue. I just got some free time and figured I'd get it done.
There is a quirk that I'm not sure is worth handling, so I didn't - when the session file gets created for the first time, and you close Lorien without any changes to the default project, it will save the session as "" in the file. This doesn't affect anything, and everything opens just fine, but I thought I'd mention in. Otherwise I think it's ready for review!

And once again, thanks for making Lorien! I'm using it almost daily now. 😄

Thanks! I hope i have time this evening to check it out ;)

Looking good. We should probably encapsulate this functionality in a SessionManager singleton similar to the ProjectManager. It's probably also a good idea to add a project setting to disable session loading/saving. But this can be done later. Merging this for now.

Thanks!

Now that i think about it...it's probably better not to have a SessionManager but rather add this functionality to the ProjectManager

I did think about doing that in the first place, but the reason I did it the way I did is because I've only ever seen Main.gd actually handle opening a project (_on_open_project() function). If I understand the way it works now correctly, would moving the functionality over to ProjectManager not require some back-and-forth between it and Main?

Yeah, some things need to stay in Main, but things like saving and loading sessions (array of previoulsy opened files) can go into the project manager. It's cleaner when Main.gd doesn't have to manage the session file on disk directly. In Main.gd you then just call these functions from the ProjectManager
