Issue #157: Vary header on minor version.
Issue #81: Create plugin type specific plugin process functions.
Merge pull request #157 from mateu-aguilo-bosch/157-user-vary-header

Use Vary header for minor versions.

If a header changes the output, then we need to list that header name in the Vary so proxy caches and cdns can do a decent work.
Merge pull request #81 from mateu-aguilo-bosch/81-multiple-plugin-process-function

Create a plugin process function for each plugin type.
