TODO: Implement caching mechanism to speed up the process

+ Change logic detecting if article was modified
Fixes #43

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

+ Better compileonly exit detection

image = "image.png"
leads to static/20xx/articlename/image.png
to be used for unique lead images

image="/images/name.png"
leads to static/images/name.png
to be used for unique lead images
