Python 3 support

[domibarton]

The current Python module doesn't work w/ Python3 because of several issues:

• print is no longer a statement, it's a function
• long is no longer available, use int instead of it (and/or remove the trailing L behind hardcoded numbers)
• urllib2 is deprecated

Any chance we can update the lib to py3k?

I published a very undocumented/unsupported Python2/3 version into branch 'python3-support' (experiment from December 2017)
https://github.com/websms-com/websmscom-python/tree/python3-support

I hope we will offer a complete Python3 version in near future, although our resources a limited - PRs welcome!

@reifi thanks :) I already created my own py3k-compatible class. Wanna to go a more pythonic way (e.g. use properties). My class is currently more lightweight, but I've only implemented a method to send simple text messages.

Your approach is much better for now, because you handle all the available features & options ;)

Here's my current class:

It's py3k compatible & pylint-compliant…

I also automatically convert all recipient numbers to the MSISDN format. However, only Swiss numbers are currently working! We use the class only internally, so not much effort for other countries there ;) However, we can easily remove that part!
