Custom config directory

[tpeacock19]

The configuration directory can be set by using --config-dir with input-remapper-control. However, this option is not offered with input-remapper-gtk or any of the other executables. This makes it impossible to edit the presets located in those directories.

I came across this because I have a non-standard xdg-config-home among other directories. So this defaulting to .config/input-remapper is a bit annoying for me.

I tried looking into the codebase to see how easily it would be to use the actual XDG_CONFIG_HOME variable but it seems to be a bit more involved than just a simple edit to the user.py. I think it would be great to incorporate the actual XDG_CONFIG_HOME variable as well as allowing the user to set the config directory when running input-remapper-service.

Did you look at the beta source? I am not sure how it is set up on main, but it should be relative simple to implement this in beta:

1. I think it makes sense to merge user.py into configs/paths.py they are both short and closely related.
2. update paths.py because .config/input-remapper is currently hard-coded in line 33
3. go through the source and make sure we always use the HOME, USER and CONFIG_PATH constants form paths.py and not some other hard-coded paths.

Sorry, I messed up with a previous request. Now I fixed it. Again, this is just an example of what can be done. It appears to me that paths.py will be used by the daemon as well.
