Plugin Power Saver: Allow Enterprise ASK policy users to manually play.

Plugin Power Saver: Allow Enterprise ASK policy users to manually play.

- In M42, we removed ASK (Left click to play) for plugins and
  interpreted all ASK users as BLOCK.

- For users on BLOCK via policy, the manually play option is grayed out,
  presumably because enterprise admins don't want users to be able to
  override their policies.

- This has the unintended consequence of causing managed ASK users to be
  unable to play plugins.

- That seems against admin intent, and this patch allows legacy ASK
  policy users to right click to play.

- This is a minimal patch intended to be merged into M42 and M43.

thestig: PTAL. Thanks!

This intended to be merged into 43 and 42 though I am not sure it will merge
cleanly.

LGTM

BTW, something for a potential follow-up commit that is not going to merged: I
also noticed that blocked by policy uses the "Right-click to play" message on
the placeholder, which isn't correct.
