Techies

* Removed `hiredis` from requirements.txt since it is not a hard requirement. Users who wish to take advantage of `hiredis` can always install it themselves, following the concept of `redis-py`.
* Added `MultiCounter`, a stateless multi-event counter, based on Redis `Hash`.
* Added `TsCounter`, a stateless timestamp counter based on Redis `Hash`, and making use of multiple keys to group timestamps, with auto expiration based on Redis key TTL mechanism.
* __Breaking Change__: `StateCounter` now has a new behavior when its objects are casted by `str` and `unicode`. `get_all()` is now `json()`. This change directly reflects the underlying change described in the next point. Also, `started` and `stopped` are now properties instead of methods.
* Simplified `techies.landmines.RedisBase` by factoring out its new child class `techies.landmines.RedisHashBase`. All Redis Hash based implementations now extends from this class to get unicode `dict` by calling `json()` method (previously `get_all()`), and unicode string serialization of the `dict` by casting the objects using `str` or `unicode` (both behave exactly the same).

* Added `StateCounter`, a state counter based on Redis `Hash`. To see an example of its usage, see [tidehunter](https://github.com/woozyking/tidehunterexample-2-without-limit).
* Included `hiredis` in requirements.txt for added performance gain.

* Added `QueueHandler`, inherits standard `logging.Handler` that `emit` to any standard `Queue` compatible implementations, including all the `Queue` implementations in this library
* Exposed direct accessibility of all intended APIs, for example, `from techies import Queue`; or if you will, `from techies import *`
* Behavior of `CountQueue.get` has changed from just returning the item value to a `tuple` of item value and its number of appearances in the queue, eg: `('dota', 2)`; an empty `tuple` is returned when the `CountQueue` is empty

* Added `CountQueue`, inherits `UniQueue` but the score is used as a count of item appearance, that the item has the highest count gets placed in front to be `get` first
* Behavior of all `Queue` and its subclasses' `put` and `put_nowait` methods changed from return certain value to not return anything (more Python standard Queue like)

* Python 3.2 and 3.3 supported now
* Behavior of both `Queue` and `UniQueue`'s `get` method changed from returning `None` to empty "native string" (unicode for Python 2.x, str for Python 3.x) when attempting to dequeue from an empty queue

* Initial release with Redis backed `Queue` and `UniQueue`
