Use a reasonable profile directory on Linux

[plucky wolf]

This has been bothering me for a while, but using ~/From The Depths is rather brutal, as it goes against well-established norms for where files should go, and as an immediate directory in the user's home folder, rather in-your-face annoying.

I imagine it would be a fairly simple change to use a standard-respecting directory like ~/.local/share/From The Depths?

As a temporary workaround until the devs fix this issue you can set FtD's launch options in steam to HOME=~/.local/share/ %command% and symlink ~/.steam to ~/.local/share/.steam.
