remap the text objects for ", ' and ` to go to the next string even if
the next string is not on the same line.

also add nnoremap Y y$ for good measure.

anb and friends. Like ib, except always go to the next body regardless
of if already in one.

similar mappings for an<, anB, an[

instead of starting a command around a text object, repeat the last
ranged command around that text object.

So one can now do something like

vip:sort<cr>

to sort the current paragraph, and then that command can be repeated
on a different paragraph with g:ip, and then the command is
dot-repeatable.

So typing Ziib will move the cursor to the next body and enter INSERT
mode.

Zaib will move the cursor to the END of the next body and enter INSERT
mode

Ziiw will enter insert mode before the current word
Zaiw will enter insert mode after the current word.

Ziip will enter insert mode befor the current paragraph

thus, Zi^ is semantically equivalent to I and Za$ is semantically
equivalent to A.

Zib will move the cursor back a word and enter insert mode.

All of these commands are repeatable with the dot (.) operator.

much of this same thing can be accomplished with the change operator (c)
and use of ^R^P", but that's quite obtuse, especially when working on
large text objects.

Right now, without Rahm's patched Neovim using user-defined text objects
will cause these commands to not play well with the dot (.) operator.
This is because do accomplish this, this plugin uses an operator within
an operator which is not well supported in Vim.

Adds the text object i/

this uses a new operator 'cd' which can be thought of as 'comment-y
delete'
