contacts: Allow and ignore empty e-mail addresses

Empty e-mail addresses (<gd:email address=''/>) are apparently allowed
by convention in the XML. Previously, we treated the empty address
attribute as an error. Instead, we should ignore the entire element,
treating it as non-existent.

core: Add support for ACL entries with keys

This adds support for <gAcl:withKey/> elements, allowing for
authorisation keys in ACLs, e.g. for Google Documents.

This adds the following API:
 • GDataAccessRule:key
 • gdata_access_rule_get_key()
and appropriate tests.

build: Enable automake parallel-tests

This should speed up the test runs somewhat, as well as improving log
output handling.

tests: Remove debug log storage system

automake's parallel-tests feature now automatically separates and stores
logs, and only prints them out on test failure. This is exactly what the
logging code in the tests was doing before, so the logging code can now
be simplified.

core: Add gzip encoding support

libsoup already transparently supported gzip encoding of data from the
server, using SoupContentDecoder, which is present by default in a
SoupSession. We were correctly sending the Accept-Encoding header, but
Google also require that the string ‘gzip’ be present in the User-Agent
header to enable gzip support.

Add a User-Agent header which supports this.
