Subject: Refactor automatic command registration, include more events

The new events are FocusGained, ShellCmdPost and ShellFilterPost but
they're only used when g:easytags_always_enabled is enabled (it's
disabled by default).

Users can now define their own list of preferred events to override the
defaults by setting the new g:easytags_events option to a list of event
names. I haven't documented the new option yet because I'm not convinced
it's an improvement in terms of usability over the old situation.
