Support for the Freedesktop.org XDG Base Directory Specification.

Search for .xlcore/launcher.ini and related files in descending order:

XDG_CONFIG_HOME/xlcore
~/.config/xlcore
~/.xlcore

Maybe default patches dir into

XDG_CACHE_HOME/xlcore/patch
~/.cache/xlcore/patch
~/.xlcore/patch

And game install into

XDG_DATA_HOME/xlcore/ffxiv
XDG_DATA_HOME/xlcore/ffxivConfig

~/.local/share/xlcore/ffxiv
~/.local/share/xlcore/ffxivConfig

~/.xlcore/ffxiv
~/.xlcore/ffxivConfig

In my eyes the important one is allowing to read the config from another location to allow users to avoid another app cluttering up their home directory. The rest we can configure ourselves even now. Keep the old ~/.xlcore directory to not break existing user setups.

This would be similar to how under windows xivlauncher config lives under %appdata%/xivlauncher
The home directory clutter is horrible enough as it is. Many users, me among them have hidden files permanently showing, because that's how you configure stuff on linux.

In any case, thank you guys for the work you're doing on the project.
