Remove most of the "Freedom" section and include relevant part in preamble

The "Freedom" section is very verbose and its purpose for the Code of Conduct
is not entirely clear. The most relevant part seems to be the last few
sentences (basically "these rules are necessary limitations to create a
functioning community"). Extract these and move them to the preamble, remove
the rest of the section.

-### Freedom
-
-_Liberty_ is the state of being unencumbered by oppressive authority, whereas _freedom_ is the
-ability to demonstrate self determination. Therefore, we must all sacrifice a small degree of
-liberty in order to enjoy certain freedoms. While the free and open exchange of assistance, speech,
-ideas and opinions is highly regarded and encouraged in the Arch community, it must be noted that
-the freedom granted to participants is not unbounded; rather, it is _relative freedom_. It
-co-exists, along with the entire Arch Linux distribution, within the boundaries of the above
-guidelines and principles. Complaints of censorship or intolerance are therefore baseless and
-unfounded, since this necessary framework must simultaneously provide reasonable limitations. To
-illustrate, we are aware of the physical laws which govern energy and matter, yet we do not
-complain of their oppression. Instead, we recognize that such laws are essential for our welfare.
-Likewise, the Arch community's high standards reflected in these guidelines regulate community
-freedom for the common good and protection of all. The key, then, to true freedom in this community
-is to cultivate benevolence toward others and to harmonize our attitude with the Arch Way by
-bringing only benefits to our peers. This allows members to satisfy all contributive impulses
-without aggravating themselves or encroaching on the freedom of others. Embracing the above
-principles and obeying the guidelines therefore benefits the entire community by providing freedom
-from the disorder and other oppressive, harmful and negative consequences of a more chaotic
-approach.
