Back to development for the next patch release.
Promote Redis 2.8 to a standalone server profile.

We still need to populate this new server profile with the
recently added new commands for Redis 2.8.

The next development version has been set to Redis 3.0.
Add link to CONFIG REWRITE (Redis 2.8) in phpdoc for CONFIG command.
New command: SCAN (Redis 2.8).

See http://redis.io/commands/scan for reference.
New command: SSCAN (Redis 2.8).

See http://redis.io/commands/scan for reference.
New command: ZSCAN (Redis 2.8).

One test is currently marked as skipped because it makes
Redis crash when the specified MATCH pattern returns one
or more elements.

See http://redis.io/commands/scan for reference.
New command: HSCAN (Redis 2.8).

One test is currently marked as skipped because it makes
Redis crash when the specified MATCH pattern returns one
or more elements.

See http://redis.io/commands/scan for reference.
Deprecate Client::pubSub() in favor of Client::pubSubLoop().

Client::pubSub() still works like usual by returning a new pub/sub
context, but it is now considered an alias of Client::pubSubLoop().

This change is necessary in preparation for the next major version
of Predis where Client::pubSub() will be used for the new PUBSUB
command introduced in Redis 2.8.
[tests] Minor tweaks, no actual changes.
Update CHANGELOG.
[tests] Handle failing test on OS X.
