nginZ 1.3.0

<i>Currently, this branch is named like new version. In future (for 1.4.0+) all will be at <code>n.n.n-wip</code> branches.</i>

This is just a new version of **nginZ**. New nginZ is coming as **mobile-first**, optimized, light and extensible framework.

Supported browsers (includes iOS and Android versions):
- Chrome
- Firefox

- Safari

## Main

- [x] Reorganize repository.
- [x] Add `.editorconfig`.
- [x] Remove all pages. Pages is excess, its deprecated for framework.
- [x] Backup and remove backports repository. All feature versions will be developed in main repository in WIP branches.

## Docs

### Documentation site

**Sorry :worried:.** Documentation site is delayed for future releases.

### Wiki

Realy worried, but cannot add 1.3.0 docs. I don't want to dissociate wiki (from 1.4.0 this framework will look like something other).

### Readme

- [x] Change Readme's format from plain text to Markdown.
- [x] Simplify Readme.
- [x] Remove *"TODO"* section. All feature specs will be in pull requests.

### License

- [x] Switch to MIT license.
- [x] Change format to Markdown due to the formatting.

## Font

I wanted to include the Font Awesome in my project. Problem is in code / font size, it's too big and will make bloat in framework. So go to http://fontawesome.io/ and download font if you want to use that. :smile:

## Styles

Styles is coded in LESS, because of its features. You are able to use LESS variables & mixins.

Also, design is now **flat**. It doesn't mean that styles doesn't have any skeumorphic thing, but it means that's main orientation flat.

- [x] Mobile-first!
- [x] Use Normalize.
- [x] Organize styles.
- [x] Switch to flat design.
- [x] Make a color pallete.
- [x] Comment code.

### New components

- [x] Add tables.
- [x] Add buttons.
- [x] Add forms.
- [x] Add menus (includes pagination).
- [x] Add image classes.
- [x] Add responsible 12-column grid system.

### Browser support

- [x] Drop IE support. Only IE thing that will left in framework is Normalize fixes for IE.
- [x] Drop support for FF 3.6.

### Misc

- [x] Remove Z3D. It doesn't apply new flat design.

## PHP

- [x] Add new functions.
