nvim/plug: +telescope.nvim@0.1.x, -fzf, -fzf.nvim

This commit removes (direct) FZF plugins in favor of telescope.nvim,
which provides a significantly nicer, native experience in doing fuzzy
searching.

The primary out of the box method for interacting with Telescope is
through the <C-Right> super key, which opens a 'meta-menu' of searchers
that you can choose from.

Some of the more interesting options are 'find_files', 'live_grep_search',
and 'lsp_symbols'. Note that you can use fuzzy searching for these. For
example, the chord <C-Right>ff<CR> brings up the 'find_files' menu.

Users are encouraged to create their own key maps for commonly used
searchers.

Also ignore Telescope windows in pear-tree as pear-tree's <CR> bind seems
to interact poorly with Telescope usage of <CR> (i.e it blocks it completely),
so we disable it
