Provide worst and best rating values in tokens

It works but
best and worst values are determined as constant in the patch(100/20). Shouldn't them be calculated as the lowest and highest of all evaluations? Rating and ratingCount values are ok.
+1 for RTBC

Hi @Graber, @init90,
Fix the issue and created MR. please review it once.

@sarwan_verma: What's the difference between your MR and the patch? Did you try the patch - how did it work? Perhaps you can write a test case for these new tokens if this is something you would like to see added?

Patch for alpha-5 version.

Comment #8 patch has filename typo issue.

Added updated patch.

Thanks for working on this. It'd be great to get even a super basic test for these token in please, as @TR mentioned in #7.

Bumping back to NR for the tests, but also to hopefully get some other eyes on it.
