Option to export/import config

[dimateos]

I used to have a txt file with my list of URL and mappings like: the following, then I updated it and copy pasted in the config.

...
# DOCS
regex101.com@@DEV-docs
devdocs.io@@DEV-docs
readthedocs.io@@DEV-docs
#docs@@DEV-docs
# cpp
cplusplus@@DEV-docs
cppreference@@DEV-docs
hackingcpp@@DEV-doc
...

Now this seems no longer possible with the input boxes in the config...
IMO the previous large text box was way better, who wants to write MANY sites one by one? but ok

I guess the next step would be to provide an export/import of the config file, this way we could facilitate backups and also write manually in the exported file like before.

❓ BTW now that there is a part of the setting dedicated to "Custom Project Names", does the older approach with @@ after the URL still works?
