Add missing Show instances.  Closes #12.

This also fixes the ISet instance to match the others and adds Trvrsbl instances.
We also add a Show instance for Generic.AFoldable.
Also, we add a couple more tests.
This passes all 41 test cases (sequentially)
Add missing file to .cabal.  Release candidate for 1.0
Minor tweak to the name in the .cabal
Add source repo to .cabal
Nice! cabal supports a subdir for the source-repository
Fancy, fancy: include the git tag too
Edit pass over most of the haddocks.
Merge branch 'master' of github.com:iu-parfunc/lvars

Expose `QPar` in Control.LVish.Internal, get rid of it elsewhere.

This'll make the docs more understandable.  Otherwise we have `QPar`
turning up in lots of types with no explanation of what it is.
Haddock polishing.
Do the 1.0.0.2 release
Minor ammend to 1.0.0.2: link the docs mirror
