New functionality to charge the job seekers

Except of charging the employers (companies posting jobs), the administrator has now the possibility to turn on or off from the administration panel the functionality allowing to charge also the job seekers. He can create job seeker packages and charge them a recurring monthly or yearly fee (depending on the package selected by them) or charge them with credits (the job seekers can buy credits and then be charged 1 credit for every job they apply for).
