WIP: Refactoring rss-reader.py

There's a lot of refactoring in rss-reader.py. I've done this:
* Lines < 80 columns
* using # for comments (instead of """)
* removing unused imports
* more descriptive variables

The above was the "easy" part.
Next:
* Refactoring on BaseBlogs, but that class is in utils.py file.
* Some pythonic approach 
* cleaning up unused variables (perhaps was using on testing or while it was developing the script)
* more tweaks while I go deep in this.
