App#processors, generators and analysers instead of singular, and each one is a register
Content#process!, generate! and analyse updated to use app's get_generator, etc. methods
Fixed Job Steps re. use of content
Content#store
Job#store delegates to Content
unused method opts_for_store
no need for Job meta specs
Job takes mime_type from Content
moved b64_data into Content
better error
app spec passing - App#store working
Updated imagemagick plugin
UrlAttributes#extract
slightly cleaner url_for logic - more logic put into Server
