Minifier resources and other updates

- Updated the Base controller class to go through a more logical process
  flow
- Since Bootstrap v3.0, the responsive CSS has been merged in with the
  main CSS code, so there is no need for the responsive option
- Added minifier resources to minify certain types of files
- Extended the standard HeadLink and HeadScript view helpers to combine
  the files, and minify this code using the configuration options in the
  minifier resource. It uses hashed filenames to store bundles, and it
  uses modification time checks to see whether bundles need to be
  regenerated or not.
