Add Render Distance option. (#675)

* FOV option without debug menu

Now located in Graphics section.

Based on the FOV thing from discord idk

* language

* render distance option for graphics menu

* oop

* swf files on media

* revert changes on language selector

* nvm it was actually easy to fix

* forgot this

* Final probably

Fixed visual bug and made the chunk updates depend to your view distance.
