Rename attribute core_or_elective to mandatory.

The following commands in debug mode will fix existing databases:

from zope.component import getUtility
from zope.catalog.interfaces import ICatalog
from zope.intid.interfaces import IIntIds
import transaction
sm = rootfutminna?.getSiteManager()
cat = sm.getUtility(ICatalog, name='certcourses_catalog')
cat.values()[0].documentCount()
results = cat.apply({'course_code':(None,None)})
uidutil = getUtility(IIntIds, context=cat)
for r in results:

... o = uidutil.getObject(r)
... o.mandatory = o.core_or_elective
...

cat = sm.getUtility(ICatalog, name='coursetickets_catalog')
cat.values()[0].documentCount()
results = cat.apply({'code':(None,None)})
uidutil = getUtility(IIntIds, context=cat)
for r in results:

... o = uidutil.getObject(r)
... o.mandatory = o.core_or_elective
...

transaction.commit()
