FEX does not comply with the "XDG Base Directory Specification"

[kuruczgy]

According to the spec:

$XDG_DATA_HOME defines the base directory relative to which user-specific data files should be stored. If $XDG_DATA_HOME is either not set or empty, a default equal to $HOME/.local/share should be used.
$XDG_CONFIG_HOME defines the base directory relative to which user-specific configuration files should be stored. If $XDG_CONFIG_HOME is either not set or empty, a default equal to $HOME/.config should be used.

But if both of these are unset, FEX creates its config directory at $HOME/.fex-emu, instead of under $HOME/.config.

Also it seems that if $XDG_CONFIG_HOME is set then $XDG_CONFIG_HOME/.fex-emu is used. I think $XDG_CONFIG_HOME/fex-emu should be used instead, since this is the convention that pretty much every other application follows (not creating hidden directories under $XDG_CONFIG_HOME).
