(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
Previously we highlighted symlinks as one item (NERDTreeLink):
symlinked_file -> /path/to/target
Split this out into 3 highlight groups:
* NERDTreeLinkFile
* NERDTreeLinkDir
* NERDTreeLinkTarget
So we have:
symlinked_dir/ -> /foo/bar
-------------- ***********

NERDTreeLinkDir NERDTreeLinkTarget
Similarly for file links - with NERDTreeLinkFile instead of
NERDTreeLinkDir.
This allows users to modify how symlinks are highlighted. E.g. to make
them appear as normal files/dirs they could add this to their vimrc:
hi link NERDTreeLinkFile NERDTreeFile
hi link NERDTreeLinkDir NERDTreeDir
hi link NERDTreeLinkTarget ignore
