GMD saving produces malformed result

[in1tiate]

Describe the bug
Saving GMD script files causes them to become malformed and unreadable.

To Reproduce

1. Open any GMD file. I used the opening scene from PW:AA - Dual Destinies.
2. Make an edit to the file, and save it.
3. Attempt to open the saved file in Kuriimu.
4. See error - Kuriimu believes there are no supported plugins to open the file.

Expected behavior
Saved files should be readable and not malformed; Kuriimu should be able to open its own saved script files.
