Enable netrw (#394)

* enable_netrw: source lv-globals before plugins and add nvim_tree_disable_netrw to lv-globals, otherwise netrw is never enabled.
If netrw is not enabled, netrw-externapp functionality, things like gx and gf to follow http links do not work.

* enable_netrw: add nvim_tree_disable_netrw to the lv-globals O object and set it in settings && source settings before plugins
