Made the CaptureCache cache pattern implement EventManagerAwareInterface. Also made set() trigger a set.post event which makes it possible for the user to know what the saved file name is.

This reverts commit 9d415eab2ea0c6b0690c5fecf76d82c55c13d767.
New public method getFilename() and supporting unit tests.
Updated component packages to add branch-alias

Now that we have per-component repos, we need the ability to install
dev-stability packages. Currently, this can only be done if you specify
dev-master (which is auto-enabled via packagist), but not via dev-develop.
Additionally, you cannot specify version strings like "2.1-dev" or "2.2-dev", as
those aliases do not exist.

This patch adds dev-master and dev-develop aliases for each component.
Prepend $publicDir to getFilename()
