Set save location for Backlog data

[lewri]

Currently Backlog seems to save its data in C:\Users....\Appdata\Roaming\Backlog. This currently poses a problem on machines that delete user profiles on shutdown, which means any boards are lost.

I would like to suggest the save/data location can be set for backlog's data through its settings. Failing that, the default save location for Backlog should instead be inside the program's folder rather than appdata (e.g. under a folder called data), especially if Backlog is designed to be self-contained.

I just realsed this is a dupe of #31

My bad 😛

@lewri default save data location can't be in program's folder due to constraints on MacOS. I need to investigate options here, though.

closing since as you mentioned it's dupe of 31 :)
