Add 'G' keybinding to folder and search view that triggers external poll

The new functions first check if an external poll script has been defined in
the variable 'notmuch-external-refresh-script and if yes, runs that script
before executing the existing refresh function (which is bound to '=')

This can be used to have 'G' mimic the mutt behavior of polling an external
mail server - or if the mail polling is already automatic, it can trigger
the call to notmuch new and any necessary automatic tagging of new email.
