Improvement: Set the correct activation events

[DrMerfy]

Currently we are using * as the activation event, this causes the extension to be slower.

We should set some more specific activation events.

This may relate to #33 - @DrMerfy Did you checked which activation events would be correct?

[DrMerfy]

Hey @GitMensch probably the best option is to use the onStartupFinished event, it should improve loading performance by some. Another idea would be to let it enable when the toggle command is trigered but that would mean that the user will not have access to the typing mode indicator before triggering the command.

Pushed the changes (and a slightly adjusted icon to reflect the project in general) in master. Could you please take a look that it works in your environment as well with the adjusted activation events?

agreed.

LGTM, also for use with remote workspaces; so time to update ChangeLog and release, I think :-)
