Move spellcheck code out of module tree

@eyecon:
Please explain "This will prevent new versions by drush from removing required code". Do I understand correctly that upgrading the module using drush wipes out the included directory?

I agree it is better to put spellchecker plugin where it belongs (either under tinymce/plugins, or separately under libraries). However this module was written before WysiwygAPI moved editors to sites/all/libraries. I'm just giving sun working on WysiwygAPI some time to stabilize the code, and form fully functional infrastructure, like finishing project/libraries.

tagging "Libraries"

Getting closer... Libraries API got 6.x-1.0-alpha1 on Dec.30 '09. I'll wait couple more weeks / closer to beta.

Fixed in 6.x-1.x-dev. Please test and post your results here.
