Prevent the "Post a question" button from being clicked more than once to avoid multiposting

[Calinou]

Using some JavaScript code, we should disable the "Post a question" button once it's been clicked once. This would prevent users from posting the same question twice because they double-clicked the button. This is an issue we regularly encounter on the Godot Q&A. It's probably best fixed in the theme since this is mainly about client-side interaction, although a server-side check could also be added in Q2A itself.

I can work on implementing this feature if this is desired.

This sounds like a good idea. It can be implemented using JQuery to disable the button once licked.
