1. Not building without build/theme directory (race condition)
2. Wrong defaults for contentdir
3. Other bugs caused by those. Fixes #32 and #33

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

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

+ Better compileonly exit detection

image now allows two different values for image url

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
