Changelog for hoist-error-0.2.0.0

0.2.0.0

Trying to make things agreeable for removed modules (Control.Monad.Trans.Either) and new instances (Control.Monad.Except(T)).
Applied the stylish-haskell hammer, and may remove unicode syntax for the proper hackage release.
Update readme, added tested-with to cabal file to prepare for travis CI integration.
Added travis yaml, and tested-with to cabal.
Updated gitignore file.
Removed 7.6 from tested GHC versions, and removed a command from travis to change to a directory that doesn't exist.
Moved the lower bound of mtl to 2.1 to permit building using transformers 0.3 for slightly older GHC versions.
Added CPP to not include Except instances unless MTL is min version 2.2.2. Added generous bounds to either package.
Add ErrorT instance for pre-mtl-2.2.2.
Added concrete type examples to Haddock, ala lens examples.
