Dev fix: Undefined variable (JSHint)
Dev: Small size reduction in SSP parameter build

- Saving of just 269 bytes in minified file, but non-the-less welcome
Examples: Updating examples for the new `ajax` property

- Note that this update is not complete, just the initialisation is
  done. The examples will shortly be rewritten to be more modular when
  this will be completed (i.e. the code shown on the page will be
  updated)
