Don't detect and redirect language by default

Hey @Cinamonas,

I agree with your changes here, that's already on my todo list as well.

According to semantic versioning, new version should be 2.0.0 though, since this is a breaking change.

Oh yeah, it was a temporary a quick and dirty solution ;) Nice to hear that you plan to implement it 👍

My plan for the major update I'm currently working on is to no more force redirecting (if no valid langauge is detected) - instead the extension will offer the following configuration-options to control redirection behaviour:

1. Never redirect
2. Only redirect if a matching language is found
3. Always redirect

While option 1 and 3 are pretty self-explanatory option 2 is easier to understand when having a look at the upcoming "language-detection-stack" explained here. Choosing this option means the following:

If no distinct valid frontend language-code was detected in the URL (either as query string, in the path or by domain-mapping) the extension will try to find a matching language elsewhere. There are two methods (cookie and browser settings) that could deliver a matching language and having selected option 2 simply means that a redirect will only happen if one of these methods returns a matching language. Meaning that visitors, that don't seem to accept any of the offered languages could be offered a list of all available languages instead of simply redirecting them to the default language.

Another configuration-setting I plan to offer is the way how redirecting happens. According to the different url-structures explained in the language-detection-stack it makes only sense to support all 3 of them:

1. domain.tld → domain.tld/xy/
2. domain.tld → domain.tld?language=xy
3. domain.tld → domain.xy

While options 1 and 2 will simply work out of the box option 3 will require another step - setting up your own domain-language-mapping. For a better understanding what that's about I'll simply include a preview-screenshot of the current state of version 2's configuration-settings:
