Had to create dummy init functions at some places since the owner of a package
is the last layer that defines the init function of a package. And a package
can be installed only if it has an owner.
Some elfeed commands can operate on a number of entries, based on the active
selection. When selecting entries with evil (visual state), the bindings for
these commands are shadowed by visual state bindings, and can't be accessed.
To fix this, the affected elfeed bindings are explicitly defined for visual
state.
