perspective.py v0.1.0

This is the initial release of perspective.py library. The code is pretty simple thereby I don't think there are lots of bugs; but if you find any or if you have any suggestions, feel free to create an issue in Issues tab or make a pull request. Current features in this version follow as:

• Making an analysis request to the Perspective API with requested attributes and specified language.
• Being able to correct spelling mistakes in attribute names and languages in analyze command arguments.

I will upload the library to PyPI soon.
