support python 3.x

[yyuu]

Please support Python 3.x.

Unfortunately, this pull req will effect fluent-logger-python to lose compatibility with Python versions prior than 2.5.

Thanks for your pull request. I'm now researching whether or not we should support Python 2.5.

Could you describe what makes it difficult to support 2.5? Just curious.

BTW, i got a comment below from @methane and am inclined to drop 2.5 support. > https://twitter.com/methane/status/237468419094622208

It's based on syntax incompatibility around try ... except clause between Python 2.x and Python 3.x.

Python versions prior than 2.5 accepts following syntax to capture raised exceptions (e).

try:
    foo()
except Exception, e:
    bar()

On Python 3.x, we have to use as keyword to do same as above. Python 2.6 and later versions can handle both form of them.

try:
    foo()
except Exception as e:
    bar()

Since this is an issue of syntax, it is hard to support both of them.

I understand what you mean, and yeah it's a bad idea to support Python 2.5 anymore. Thanks for the pull request!
