Update philosophy section with Manufesto

[dhimmel]

We should update the Philosophy Section to include a mention / link to https://manubot.github.io/manufesto/. Currently, the section reads:

manubot.org/index.html

Lines 242 to 284 in 5dce1aa

	Our Philosophy

	<p>
	Manuscripts are the primary basis of scholarly communication, yet the
	process of creating them has not kept in step with the advancement of
	technology or the evolving best-practices of science.
	</p>
	<p>
	Traditionally, authoring of manuscripts takes place in a closed manner.
	While most scientific material is eventually distributed to some kind of
	public medium, the process of developing and reviewing the material is
	usually done in private, contained to a handful of individuals. The tools
	used are often outmoded, restrictive, and overall poorly-suited for the
	task of collaborative, scientific writing. The time it takes to review and
	publish can be
	<a
	href="https://www.nature.com/news/does-it-take-too-long-to-publish-research-1.19320"
	>unreasonably long</a
	>.
	</p>
	<p>
	We believe that this process is antiquated and must be reformed. Good
	science depends upon many things that the conventional approach doesn't
	provide: A diversity of input and perspectives. Spontaneous and
	cross-discipline contributions. Organic and wide-spread discovery and
	dissemination of knowledge. The fostering of a free, global information
	commons. A method of real-time, continuous science, performed entirely in
	the open.
	</p>
	<p>
	Current technology easily affords huge advantages over the old way of
	doing things, both in convenience and in the quality of the result.
	Manubot is a solution to the past and a push towards a future ideal, where
	scientific writing is transparent, reproducible, immediate,
	permissionless, versioned, automated, collaborative, open, linked,
	provenanced, decentralized, hackable, interactive, annotated, and free of
	charge.

@vincerubinetti do you have a preferred implementation of how we should mention the Manufesto?

[vincerubinetti]

Maybe another one of those big red buttons that just says "manifesto" or "our manifest" along with an appropriate font awesome icon:

Sounds good to me. Bullseye works
