Improve testing method

[halfdan]

I think its common practice for Python projects to execute tests by calling python setup.py test, this was not possible before so I implemented this. Not sure if some lines in base.py are unnecessary now, so you might want to check that.

It would be great to add automatic test builds using Travis-CI to this project. If you like I can work on a solution to get a running Piwik installation onto the Travis-CI server so we can automatically test the library each time a commit happens.

Changes:

• Changed setup.py to support the test command. You can now run tests via python setup.py test
• Defined test suite in piwikapi/tests/__init__.py

Thanks Fabian, just fixed it with a slightly modified commit.

Any reason why you don't want python setup.py test to work? Afaik this is common practice for Python projects..

I closed the pull request because this issue is fixed. Thanks for your patch, but I chose a different approach.

That is completely fine - just curious why :)
