Allow user-defined RO indicator.

(inspired by overwriting g:NERDTreeDirArrowCollapsible/Expandable)

Replace instances of the RO string with a variable that the user can
override. Useful for custom unicode glyphs, i.e. Font Awesome.

* Initialize variable g:NERDTreeGlyphReadOnly = "RO".
   -> plugin/NERD_tree.vim
* Replace instances of 'RO' with g:NERDTreeGlyphReadOnly
