Do not overwrite existing header with POST

Existing 'application/x-www-form-urlencoded' content-type headers are no
longer overwritten when applying POST headers to a request before
sending. This allows developers to set custom attributes on each request
(e.g., charset).

Fixing typos in the FAQ

The extra trailing quote marks are unnecessary/invalid, and break the syntax highlighting in the example (and would cause a syntax error in actual code).

Improving URL encoding of path and query.

This commit updates path and query string encoding to better handle
strings that are already percent encoded, and now allows for all of the
characters valid for paths and queries specified in RFC 3986 to be
present in a URL without being encoded.

Query strings should be treated an un-encoded by default.

This change updates query strings so that they are treated as un-encoded
values by default where the value represents an un-encoded value to send
over the wire. A Query object then encodes the value before sending over
the wire. This means that even value query string values (e.g., ":") are
url encoded. This makes the Query class match PHP's http_build_query
function. However, if you want to send requests over the wire using
valid query string characters that do not need to be encoded, then you
can provide a string to Url::setQuery() and pass true as the second
argument to specify that the query string is a raw string that should
not be parsed or encoded (unless a call to getQuery() is subsequently
made, forcing the query-string to be converted into a Query object).
