title: How to unload all the plugins from vim and change VIMRUNTIME?
body: <p>I have an account at my hosting providers server and I can't install my own copy of vim.
  So the only personalization I can make is editing .vimrc in my account, but it won't suffice</p>
  
  <p>What I'd Like to do is:
  on startup I'd like to unload all the plugins and loaded stuff, and tell vim to use other folder as its' runtime.</p>
  
  <p>Any idea how to aproach it?</p>
