Workout better semantic versioning pattern

[ryanolee]

Currently it is hard to follow what versions of the repo support which twig versions

[alexwilson]

This wasn't ever really a consideration, IIRC the Twig_Extension pattern was supported in both v1 & v2 which were supported by Symfony 2.x.

Newer versions of Symfony (3.3 and beyond?) support webpack natively and the purpose of this bundle was to backport that.

For simplicity it's probably best to add some documentation with a migration path to the native functionality, and bumping the current version to 1.0.0 - to encourage further API-surface-creep. (which apparently we never got around to!)

For what it's worth https://github.com/bluetel/webpack-manifest-bundle/releases/tag/0.7.2 deserves merging back into trunk!

Sounds like a plan. I will be away for a week but look to clean this up and further action this when I am back :D

Have a lovely break! 😄
