nvim: Fix telescope grep

Fixed grepping for telescope to work again, and work with the native
'live_grep' function.

Replaced fzy extension with precompiled fzf since I have that installed
anyway.

Changed some theming around so I have a fast, minimal file switcher
instead of the big window by default. Can still call the big preview
window through the Telescope command if need be.
