Send data to 4CAT behind a web server in a subfolder structure (i.e. example.com/4cat)

[rahcor]

When 4CAT is behind a web server in a subfolder structure (i.e. example.com/4cat), the line 96 of interface.js ignores what is after the '/', thus Zeeschuimer throw an 404 error trying to connect to the 4cat API. A temporary solution is to open the web browser console and manually set the variable: background.browser.storage.local.set({'4cat-url': 'https://example.com/4cat'})
