app: export global functions

The single Aerc object is passed around in almost all command functions.
This hinders readability.

Store the single Aerc instance as a global variable. Export public
functions from the app package to access methods of that object. Remove
all explicit references to *app.Aerc and replace them with calls to
these functions. For references to private/unexported fields and
functions from within the app package, directly access the global aerc
object.
