TODO: fix lightboxes

Moved all not yet promisified files to sitegin/legacy

Config - returns configuration
ReadFiles - reads files from config.articlesLocation
Print - prints everything it gets

Created jobs which will replace sequence with promise-based api

removing need for separate repo

- Changed favicon
- Article width is more narrow

- When paragraph has image its not p but div.has-image
- You can specify image dimensions in markdown

- Misc crash fixes

This allows to synchronize multiple browsers
(for example Chrome and FF)

This allows it to run without compiler
(namely VS on Windows).

Image minification won't work when LWIP is
not available. App will warn you about it.

It will also generate lightbox for every image
even those which are under 512.

It also normalizes every path to path/to/file
from path\to\file.
