with navigation style preference.

<<Amendment 3 24/09/18>>
Moved 'heirarchy' prefix/keybindings from 'SPC m h' to 'SPC m <g/p> h' for
consistency with navigation style preference selections.
Added 'members' prefix under 'SPC m <g/p> m'
Moved 'lsp-ui-imenu' from 'SPC m g m' to 'SPC m g M'
<<Amendment 4 20/10/18>>

<<Amendment 6 01/11/18>>
Reased. Updated for compatibility with upstream changes in lsp-ui.
<<Amendment 7 02/11/18>>
Corrected oversight -- was still binding some peek funcs under 'p'
rather than 'G'. Moved backend keybindings to 'b' (for backend)
rather than 'l' (for lsp)
<<Amendment 8 06/11/18>>
Documentation corrections -- based on feedback from sdwolfz
1. Fix `short-name` for directories. Previously it was empty string.
2. Remove redundant check for existing buffer:
1. `(get-buffer new-name)` always return `nil`, because `new-name` is a path
to file, not a file name.
2. `(find-file new-name)` handles this situation.
3. `dired-rename-file` handles this situation as well.
3. Use `dired-rename-file` to do the dirty stuff.
1. Renames files and directories.
2. All associated buffers are updated. If you rename a directory, all buffers
that were visiting files from that directory now visit files from new
directory.
4. Properly handle recentf list update for directories - all files from the
renamed directory are removed from recentf list and the same files but from
new directory are added back.
problem:
`'face 'minibuffer-prompt` and `new-name` are shown with an orange color,
and `describe-char` shows that they have the face: `font-lock-warning-face`
solution:
adding a newline before them removes the orange warning color
