Add support for '~/' in config imports

This allows the configuration file imports to start with '~/' and
resolve relative to the user's home directory.

There is no support for '~user/' or '$HOME/' or any other shell
expansion. However since paths relative to the home directory should be
sufficient for everything, this provides a very simple solution without
any significant drawbacks.

Fixes #4157.
