continue breaking down the epic autoload module
Add 2 new classes and move code into them from autoload: * NERDTree. Each nerdtree buffer now has a NERDTree object that holds the root node and will old other util functions * UI. Each NERDTree object holds a UI object which is responsible for rendering, getting the current node, etc Still a fair few methods to sort through in autoload (many of which will end up in the above classes) - need sleep though.
