nvim: Remove pencil to fix relative cursor movement

Cursor movement works better for soft-wrapped prose files now:
When just using j/k to move vertically, the cursor will jump between the
different parts of a single wrapped line. That means you can easily move
anywhere you want on your lines, exactly as it's shown to you.

If, however, prefixing your j/k move with a number to move a relative
number of lines, it will no longer take wrapping into account. That
means you can not jump instantly to *any* part of a wrapped lines,
however on the other hand the relative line numbers on the side never
lie now: You will jump exactly as many lines as are shown on the side.
This is a tradeoff I am happily willing to make.

Additionally had to remove vim-pencil to get the movement to work, but
since it did not provide any visible pros anymore, this should not be a
big issue.
