Improvements in the gitignore file.

Some line were been added to avoid git from including hidden and temp
files generated by some text editors.
Whitespace remotion.

Removed whitespace from two lines in the comments_index template.
New comments added.

New comments were added in order to test the new way a page is rendered
after a comment insertion.
The main header is not always visible anymore.

I think that, since the main header has just a title, and doesn't add
any functionality other than displaying the page's title, there's no
need for keeping it visible all the time.

We're not on Facebook which has a real navbar. Furthermore, if the main
header is always visible, links to sections of the same page won't work
properly since the header will override the top of the page.
Djago's collected static folder now ignored.

The only satic folder we have to care about is the one we've made.
There's no need for including site_media in any commit since it can be
updated at any time by a simple "manage.py collectstatic".
Every comment has now a link to itself.

Every comment has a link pointing to its beginning so, when a comment is
successfuly inserted, the page will be reloaded and the new comment
displayed immediately.
Replacement of Django's native text field by TinyMCE's HTMLField().

TinyMCE offers an improved widget for text fields, including support for
all basic HTML text formatting, such as bold, italic, underscore etc.

The content attribute of the Post class is now an istance of
HTMLField(), which allows the administrator to create and edit blog
posts more easily.

Proper measurements were taken in order to include and configure
TinyMCE, which was done through some modifications the in the urls.py and
settings.py files.
