Django 1.8's string freeze is here, time to update the Hebrew translation as django-core was on 93%

Standing at 100% translation after a couple of days:

• django-core
• django-formtools - Removed from django.contrib
• django-people (the website)

Left in the cold for lack of time:

• django-localflavor - couldn't find Hebrew names for many of the cities (stands at 46%).
• django-docs - A lot to translate (stands at 1%).
