HOTFIX: added Media back to profile defaults. Media button was missing.

## Ready State: Yes

The media button was missing from the editor profiles, and wasn't showing on the available buttons, traced this to this commit:  https://github.com/imagex/imagex_wysiwyg_profiles/commit/2c696956a2e6d364d2f901fd5b23f5414a17e32c  which removed Media from configuration.

I updated the one line to add back Media.
