Loading bars

I was really impressed by that loading animation by @Marcel so I decided to implement it with HTML+CSS combo.

You can play with variables at the begining to get different results. For example something like this:

http://codepen.io/MaxStalker/pen/eLkKB

I also decided to add some new software/technologies to the mix so I could study/practice, while doing this piece:
- Emacs - to prototype and get used to keyboard shortcuts. Like it so far.
- SCSS - for variables and "for-loop" to add different delays to nth-child.
- Jade - I decided to use this templating engine instead of javascript to add fixed amount of blocks in a loop.

TODO: Clean CSS. Add top part. Add custom easing function.
