Fix #60: restore build with GHC 7.10 - 8.8

good bye (for a long while) to the very recent LANGUAGE extensions BlockArguments and ImportQualifiedPost
import (<>) from semigroups in testsuite for GHC <= 8.2
guard ghc-option -Wcompat under impl(ghc >= 8.0) conditional
document supported GHC versions in tested-with field

Thank you! Those extensions are not that important to break compatibility with older GHC versions. Not sure about 7.x (does anybody still use it?), but 8.x must be supported.

Thanks for the quick action!

I don't know (Ubuntu LTS 18.04 is on GHC 8.0.2);;; but as long as it is no effort, I think GHC 7.10 can be supported as well. (I am maintaining some old packages, so I have all major GHCs from 7.0 installed...)
