[api] test HTML in the API
[api] move webui as into api engine
[webui] rename project to WebuiProject

Makes it easier to grep for it
[api] move the rails script into the rails4 bin/ folder

My IDE won't detect the project as rails4 otherwise

[webui] remove first webui/ controller in the API

It's just one AR call now
[webui] merge Webui::Role into Role

It was just a namespace anyway
[webui] fetch latestupdates right from the database instead of API hop

This looses caching for now, but we can cache better in the API anyway
[webui] use the package model directly to save roles

Fortunately the models already check for permissions
[webui] calculate the worker status directly in the API
[webui] fix test cases

- take out some more caching (for now, to be readded in the models where
  it's sane)
- fix flags validation
- redo the travis split
- use truncation for database cleaner

(and due to rubymine insisting replace "" with '' where no escaping is
necessary)
[api] retire webui/relationships controller
[webui] calculate project#list_all right in the webui
[webui] move the rest of the webui/projects_controller
[webui] create the interconnect directly
[webui] remove the usage of find_cached
[api] make use memcached in test environment

but make sure not to reuse old caches
[webui] query the database directly for packages
[webui] remove caching support for parent_projects
[webui] move things from Webui::Person to User model
