images examples and ugly script to get mean bg color with gm module and imagemagick
added canvas and underscore, extracted pixel data for 1px borders
sorted counted colors and displayed the most used color
fixed calculation and checked how the script works with png with the same amount of pixels for all colors used on the image
removed gm module, did small refactoring
removed node-canvas module and use get-pixels instead
moved getBgColorForImage.js to /lib and made it a module reused in jobProcessors.js
small refactoring - two loops instead of 4
update status and background color in one query
use tile_set.background_color while rendering a map
CR changes: removed ' around key name
added unit tests
CR changes: used array instead of object
CR change: use array.join() once we return array not an object
CR change: fixed default value
CR change: make error more verbose in logs
CR change: got rid of underscore
removed `it`
