[epiphany] Add EphyTitleWidget interface

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 01e6a4ba12ba9f02c154c32a8f2e7bf87851e043

    Add EphyTitleWidget interface
    
    The goal is to only ever create an EphyLocationEntry *or* an
    EphyTitleBox, depending on whether or not we're in app mode. To aid in
    this, add an interface for them both to implement.
