Code cleanup.

Of note:
* io.save_all_files() does not visit each buffer to save anymore. An unintended
  side-effect was checking for outside modification (but only if the file itself
  was modified), so outside changes will always be saved over now.
* The menu clicked handler uses assert_type(), so the 'Unknown command'
  localization is no longer needed.
* When printing to a new buffer type would split the view, use an existing split
  view when possible.
* Prefer 'goto continue' construct in loops over nested 'if's.
* Fixed clearing of ui.find.replace_entry_text on reset in the GUI version.
* Fixed lack of statusbar updating when setting options like buffer EOL mode,
  indentation, and encoding.
* Renamed internal new_snippet() to new() and put it in the snippet metatable.
