[FEATURE] Support symlink on default config path

[VuiMuich]

Description of the requested feature

I put a symlink at ~/.config/eww pointing to a subdirectory of my leftwm theme at ~/.config/leftwm/themes/current/eww. Basically eww is running fine but in the logs it complains about:

2021-08-20T15:50:08.305Z ERROR eww::error_handling_ctx > Failed to initialize eww paths

Caused by:
    Configuration directory /home/vuimuich/.config/eww does not exist

I didn't want to lable this a bug, as eww seems not broken in any way.

Proposed configuration syntax

Tbh I have not looked it up in the source, how eww is checking for the config folder, but maybe adding a std::fs::symlink_metadata.file_type().is_symlink() check along a fs::read_link() might help here?

It works for me:

$ ls -l eww
lrwxrwxrwx 1 nix users 4 Aug 30 10:39 eww -> eww2

and:

cargo r -- daemon

When I open a window, it works. And there are no errors in the log

I'll close this, as I too cannot reproduce the issue here

Can confirm it works for me now as well. Maybe it was something fixed in an dependency meanwhile.

Anyhow, sorry for forgetting this was still open.
