Few Issues With GUI Editor

[kamdhenu]

1. Support for disabled keys and comments:
   .env supports disabling certain keys by commenting it out with a '#' sign, once can also add comments after a '#' sign.
   Please enable support in GUI editor, so one can enable and disable certain values. Also any data in value field after a '#' should be parsed as comment.

2. Values with spaces, must be saved after surrounding them with commas (" or ')

3. I think it's a VueJS issue (and changes are not really saved in .env), if you try to edit an entry and make some modifications to it, even if you click abort the changes are immediately reflected on the page.

Feature Request:

1. Protecting certain keys/values so that they can not be available for editing
2. It would be nice if you can add a config item where one can change the page title ".env-Editor" to something else.
