Continued a bit:
- don't return full list as the JSF seems to modify it ???
- always use this.someList and not allFoos()
- moved allMobileProviders() and hasMobileProviders() to regular controller as this one holds the cached list anyway
- renamed mobileController -> mobileProviderController
- call bean again instead of getting same (!) list: this fixes a bug that a lot contacts has been removed from the list
- careful cherry-picking this: recruiter-related changes are included and contact EJB added!
