Lingua support

[miduku]

Markdown Editor isn't usable unless primary language is selected while editing a resource. I am using Lingua as a multi language solution for modx and sadly when I select a language the editor disappears.

Additionally there is a bug when the primary language is selected: The "select file or drag & drop to upload" text at the lower left of the editor is displayed 3 times andwhen I save the resource it keeps copying itself.
