Change folder from "speedrunigt" to ".speedrunigt" on Linux

[amot-dev]

I understand from #73 that making the records path changeable is not in the cards, however, having it exist in my home folder and unhidden is a massive clutter. Clearly, one thing here does not belong:

❯ ls
Code
Documents
Downloads
Games
Pictures
speedrunigt
Videos

I know there's some effort involved with moving the location, but it would be a significant improvement to my sanity.

#224 next update. biggest problem is it should be paired with ports to all versions before release otherwise it would desync across instances.

for now you can modify -Duser.home=x/y/z as a java argument to change where global is stored if you like
