Adding a projects page
Shitload of additions.

Font-awesome was added to the repository, but shouldn't be on this
commit. I'm going to merge and fix the problems related to it this week,
so that's fine. That's another reason I'm using font-awesome via a CDN.

I created a projects page (projects/index.md) and updated some stuff in
the about me page. Simple stuff, mostly.
Merge pull request #1 from agarie/projects_page

Projects page & introduction of font-awesome
Updating Jekyll
Updated 'about me' page & added LinkedIn icon
Added post about NMatrix book
Added documentation for the Measurable gem
Changes to layout

Various changes were made:
  - The background texture is now "husk", while "mooning" was added as a
    second option for the future.
  - Decreased the width of the central container. I'll probably decrease
    it even further in the future, when I remove the sidebar in favor of
    upper links (a global navigation bar, maybe).
  - Centered the blog's title. (I really should think about a subtitle
    not involving japanese...)
  - Added a color palette to variables.less, which isn't used at the
    moment. It's for future use.
  - Removed logos, as now I'm using fontawesome's icons.
Added post about Measurable; updated docs
Updated posts' tags and categories
Trimmed big title
Updating assets

Lots of small tasks to implement a more organized asset structure:

- Moved _less to assets/_less.
- Updated rake task (`rake less`).
- Added font-awesome and bootstrap cloned from GitHub.
- Fixed font-awesome's path to find fonts (`@FontAwesomePath`).
- Cleaned onox.less and variables.less.
- The images/ directory is located under assets/ now.
- Removed font-awesome CDN call from <head>.

Now everything should work with `rake less`.
Updated measurable docs
Post about BLAS & LAPACK, MathJax
Fixing typos
Decreased line-height
UI tweaks for better readability

I added a new layout, "pages", which is currently used in the first
page. I'm thinking in creating another one for the about/projects pages.

The biggest visual change is the increase in left/right-margins for the
central panel and a bit of "fine-tuning" for its padding.

Ah, I also divided _includes/navbar.html into social/links, so I could
add the social network list to my about page and remove the right menu
at the same time.
Updated create task

The use of `categories` over `category` allows the use of more than one
category (obviously).
On the verge of procrastination
