closes #6398

... and a stealth-commit of an already introduced bug prevention system.
;)

* Wrap it into a transaction
* Use destroy over delete so dependent destroys get triggered
  and we thus don't fail on the foreign key constraits
* Check if a photos status message actually exists before accessing
  it
* Add missing dependent destroys

Use a blacklist approach instead of a blacklist approach in Profile#receive.

Remove attr_accessible from models and make specs pass.

* Dropped all references to Resque
* Moved all jobs under app/workers since that's the Sidekiq convention
* Renamed Jobs module to Worker to match new location
* Adapted all jobs to Sidekiq
* Replaced all enqueue calls with perform_async
* Dropped Resque hacks from specs and features, replaced with
  sidekig/testing in RSpec and sidekig/testing/inline in Cucumber
* Updated scripts to start a Sidekiq server
* Inline Sidekiq sinatra app
* Let Sidekiq create the actual Redis instance
* Workaround already initialized constant warnings in service models
* Resolved ToDo in one job definition by creating proper exception clases
  for some errors in receiving posts
* Added sidekiq section to configuration to make it completly
  configurable to the user
* Add Sidekiq middleware for clean backtraces
* Delay HttpMulti retry to give offline pods a chance to come back up
* Do not retry on GUID already taken and alike errors
* Be graceful about deleted posts in GatherOEmbedData

* Rename and reorganize post fetcher to fix autoloading, also let it use
  Faradays default connection so we get nice redirects
* Add initializer to load libs at a central place
* added lib dir to autoload_once paths to increase thread safety
* Moved lib/exceptions.rb to lib/diaspora/ to conform namespacing

* Throw away old system
* Add new system
* Add new example files
* Replace all calls
* add the most important docs
* Add Specs
* rename disable_ssl_requirement to require_ssl
* cloudfiles isn't used/called in our code
* since community_spotlight.list is only used as enable flag replace it with such one and remove all legacy and irelevant codepaths around it
* die if session secret is unset and on heroku
* First basic infrastructure for version information

i've temporarily removed all the arbitrary text switching for now (which is still in version control // which we will get to later)
also moved photo dimensions into a dimensions hash in photo.rb.

introduce the idea of Federated::Base. this is mostly just renaming and collasping of different federation modules, but also starting a direct hiearchy of these federation classes to make everything easier to refactor

remove cache counter for photos, as it was causing too many edge-case errors & added complexity across models

fix specs; move presence_of_content validation check into a before_destory to play nicely with federation

removed Photo#not_processed

let the user upload an image without touching the textarea, improved check in Photo#process to not yield no method on nil error in some cases
