    entryArea: Share a common spell checker
    
    We currently use GSpell's convenience API to add spell checking
    support to entries, which turns out to be quite wasteful when
    used with lots of separate entries:
    Every entry gets a separate GSpellChecker object with its own copy
    of the dictionary.
    Address this by setting up all entries manually with a shared spell
    checker object.
