adblock-fast: initial commit

* this package replaces simple-adblock package
* it was impossible to keep existing config structure and continue
  improving the simple-adblock the way I wanted, hence the new
  package name
* the migration script for existing simple-adblock config is included in
  the uci-defaults file
