Previously, we would save the location of the `G` command regardless of
whether it was used with a count or not. Thus, `34G` and `G` would both
save locations.

Saving the location of `G` isn't really useful, but it's easily
accessed. Instead, only save location when using a count with `G`. This
allows the Grappele command to be useful even after having pressed `G`.

* Update CHANGELOG
* Increment version number in help file

Turns out that invoking `G` wouldn't push your movement to the jumplist
(unlike Vim's real `G`). This was not only confusing, it was also wrong.
Just an oversight on my part that I didn't notice until now.

* Update version number in help file
* Update CHANGELOG

Don't output the mapping result in the command line when using the `G`
command.

Was handling this prevously with the `<Plug>Grappele` mapping but not
with the new one that I added in
07a75d523eadaf1027aa8bf287256602ad05f97f.

Include information about the initial v0.0.1 release.

Include a description of the plugin, installation instructions (copied
from one of my other plugins), and license information.

Create a help file with information about the plugin, its primary use
case, and information about its mappings (although one of them isn't
really noticeable as a customised mapping).

Also generate helptags.
