1.0.0-beta2 release
beta2+ increment
add the include path where ev.h is installed by libev-devel on Centos
Add CentOS libev install commands
Fix bug in varint packing that caused 0s to throw an exception
add missing unicode encoding mapping

it looks like unicode strings are not properly encoded in cql queries because of this.

cqltypes.py: change 'set' to 'sorted set'; change 'dict' to OrderedDict
Add __repr__ method to SimpleStatement and PreparedStatement. This should help
with debugging.
Throw InvalidParameterTypeError  exception if user trys to bind
PreparedStatement with an argument of an invalid type.
Modify InvalidParamaterTypeError to inherit from TypeError.
Also include consistency level in the __repr__.
missing connection check before returning it

checking if the connection still exists solved lots of random AttributeError exceptions 'NoneType' object has no attribute 'lock'

looking few lines up seems like this check is necessary
Install unittest2 as a test dependencies when running tests under Python 2.6.

Currently tests would blow up if they were run under 2.6 because they were
relying on unittest functionality which is only available in Pyton >= 2.7.

Conflicts:

	tox.ini
Use set instead of set literal, because set literal is only available in Python
> 2.7.
make blist a dependency to get sortedset; use util.py OrderedDict if < 2.7
