Update vimperatorOption with current Vimperator options:

Queried by filtering `options` object keys (strings, numbers, boolean).
Thanks to @gkatsev. Would be nice if this could be automated somehow.

    Object.keys(options).filter(function(key) { return typeof options[key] === 'string'; })

Still required some manual filter, due to internal options not exposed
in documentation and such.
