Please include stk-assets

[Buggem]

In the RPI4 repos there is no subversion package, so how in the world am I supposed to get the SVN command. This is ridiculous. PLUS, why don't you just add the stk-assets folder or whatever it is to the repo, instead of making us download it. Please reply asap.

The need to SVN https://svn.code.sf.net/p/supertuxkart/code/stk-assets stk-assets is stated in the README.md.
