Spelling error on tooltip

[novasource]

In the editor, the spell check button has the following tooltip: "Toggle spellchecker". "Spell checker" is two words, not one.

I'm not sure what the correct spelling should be but "spellchecker" is used twice, once in

wp-includes/js/tinymce/plugins/spellchecker/tinyspell.php
wp-includes/js/tinymce/plugins/spellchecker/langs/en.js

The author of the code may simply have got used to using the "spellchecker" class :-)

According to *1 both "spell checker" and "spellchecker" is correct, so no need to change it.
