Send minimized requests

[execveat]

There should be an option (controlled through Settings window and enabled by default) to minimize GraphQL queries before sending them over the wire.

GraphQL ignores some characters:

• most of the whitespace can be stripped out, apart from newlines that are signifying the end of the comment
• all commas I think

There could be corner cases when minimization might prevent a particular attack, so it should be optional.
