Support gif uploading in 0.9.4 version

[Nisthar]

Hi, I saw nodebb now supports gif uploading in its 1.0.0 version, I think.

I would like to know if i could change the file "src/controllers/uploads.js" in my 0.9.4 version as mentioned in this commit https://github.com/NodeBB/NodeBB/commit/cf00371892f4cd16a77c26b45a6d9d43c824ebad to support gif uploading?

@Nisthar Yes, You can do it

Would have been nice if we could upload gif in the about me or signature section of the profile.
