Adding a font-family option to the NamelessMC textbox

### Describe the feature

Currently, when writing new topics in NamelessMC forums, it's not possible to change the font family of the text you're writing in. With it, you'd be able to write in fonts such as Verdana, Courier, New Times Roman, etc.

I've been told to suggest this on the Github, logging it as a Git Issue. Hope it helps!
