Import posts made on WordPress
Personalization Part 2

The file tags.html generates a list of all the posts sorted by tag.
I did not like it and since i did not find any file referencing it,
i moved it to _orig_content. The file theme-setup.md is also moved
to _orig_content.

I copied tags.html to a new file named categories.html and modified it
to produce a list of all the posts sorted by category which i think
is more useful.

I modified the links section in _config.yml and removed the "Theme
Setup" and "Made Mistakes" link. In their place i added a link to
the Categories page and a "Home" link that returns to the Home Page.

Indent CSS script

The main.css script is indented so i can have a better idea
what is going on.
CSS Modification

* Code using the <pre> tag will have now have a 2px border.

* Table border collapse, cells have a small padding,
  header cells have lightgrey background.
CSS Modification Part 2

The main.css script sets some default values and then uses
media queries to support larger widths. The largest width
supported is 1024 (it uses 62.5em which equals to 1000
with the default browser font size of 16).

Most websites i see are designed for 1024x768 and use
the "standard" 960 maximum size. My monitor has 1920x1200
resolution and i find the layout quite small.

So, i added a new media query for 1280 width and enlarged
the regions and font sizes a bit. I do not know if i used
the proper values (i know one of the reasons 960 was selected
was that is has many divisors) but i like the layout better now.

A new page titled OpenPGP is added to the navigation bar.
The page uses a simplified layout and CSS theme and describes
my Key Certification Policy.
