One questionable (but practical) thing that MetaLinks have is that they announce (MetalinkChanged) when they are installed or uninstalled.

This is nice for being able to show them in the UI (and e.g. the Watcher implemented with them).

But it is very very slow��� so I now made it an option:

it is by default off, but can be turned on reflectively at any point.

e.g. the link of the execution counter now looks like this:

It has announcing enable so that the browser refreshes when it gets added or removed.
