* Change maintainer to myself, asked by current maintainer
* Remove atomic workaround, it's been fixed upstream in 1.4.0
* Install all plugins, disable those that depends on external applications
* Remove bundled pyYAML library, use package if you want to use python plugins
* Remove "unused" files in webdata directory, saves about 900k
  Downside is that some _very_ old browsers might break however since netdata
  is very heavy on javscript you still need a somewhat recent one anyway to get
  a decent experience.
