`language-javascript-0.7.1.0` should have been `0.8.0.0`

[cdepillabout]

It appears language-javascript follows the PVP. Version 0.7.1.0 was recently released, which bumps from 0.7.0.0.

However, 0.7.1.0 includes #113, which adds new data constructors to an exported data type.

I asked about this on the Haskell discourse, and it appears there is a (small amount of) consensus that adding a new data constructor requires a major version bump: https://discourse.haskell.org/t/does-adding-a-data-constructor-require-a-major-version-bump-according-to-the-pvp/3600/3

So 0.7.1.0 should have been 0.8.0.0.
