Title: Source code formatting audit.

* Substitute all `%` string operations with python's `string.format()`. There are still some `%` string operations left behind on some specific cases which will be evaluated in order to keep **all** string operation using `format()`. More info on http://docs.python.org/library/string.html#formatstrings
* PEP-8 corrections.
* Add space after commas(`,`), for example:
```python
x, y = foo.split()

'{0} {1}'.format(foo, bar)
```
* Pyflakes corrections.
* Favor single quotes over double quotes.
* Minor typos.
