Instituted more effective method for database queries.

Added a method to receive database info with one query instead of 6 by "overcoming" doctrine's lazy-loading.

Added Comment Number on Main Page.

Now, underneath the blog post, it says the number of comments each post has, and by clicking on them, you go to the page, and your browser conveniently scrolls down to comment level.

Added Files for the Sidebar's CSS and Data.

The sidebar now has a fully styled Tag Cloud, showing the most recent tags, and the more they are used, the bigger font size they are shown in.

Fetch data for sidebar.

- BlogRepository.php >> Execute queries on the database to get information on the tags, and then, using a series of arrays, get a number of how many times each tag is used.
- PageController.php >> Use BlogRepository, and read those values into PHP variables, then pass them to a view.
