Javascript error breaks TinyMCE editor

Your plugin generates a Javascript error:

Can't find variable: addFascToEditor

The TinyMCE button is added everywhere but the script is only loaded in certain areas.

Since other plugins or the theme may want to use wp_tiny_mce() in other areas, your plugin generates a Javascript error outside the post/page editing screens.

?It adds it’s TinyMCE button everywhere on the editor but it only loads it’s scripts on post/page editing screens. Since other plugins or the theme may want to use the editor in other places using wp_tiny_mce() function, it should either load it’s scripts with TinyMCE at all times or only add the button to the editor where it’s scripts are loaded.
