Continued updating docs and scripts

- queryString documentation is complete

- queryString function refined so that it returns false when there are
no query strings available.

- Updated documents styling a little (made sure that the nav toggler
doesn't have transition when switching between its sticky and non-sticky
state)

- Browser detection and the transitionEnd variables have been moved from
init.js straight into homebrew.js. This is so that you can throw in
homebrew.js and everything is already available from the get-go through
the `homebrew` object.
Updated homebrew.js

Made sure that it's using the new transitionEnd property that's in the
`homebrew` object
Fixed syntax issues
Updated docs

- Made a note to recommend using vanilla CSS over SCSS counterparts,
because I haven't had the time and opportunity to use SCSS, so it's not
as robust and up-to-date

- As not all assets have styles, I have updated each page to specify
whether or not the asset has default styles, and if they do, I list out
where they are.
