- only use one language at a time for spell check
- allow quick language change in spellcheck dialog
- if no languages selected in preferences, list all installed
  aspell dictionaries in dialog
- don't make "en" the default, use first available dictionary
- add preferences button
- auto-select first suggestion
- fix #362 crash if no dictionaries available
