zeitgeist module: Hide get_ and set_ from API

[Siegfried Gevatter]

Currently the properties of Event and Subject can be accessed as .name or as .get_name/.set_name The later functions are redundant so they should be made private (renamed to ._get_name and ._set_name).

Don't care enough as to argue with thekorn -.-.

IMHO setting the bug to invalid is the right decision. Just in case anyone looks for a solution for it in the future, use sth. like this

class Test(object):

    def __init__(self):
        self.__value = 5

    def get_value(self):
        return self.__value

    def set_value(self, v):
        self.__value = v
    value = property(get_value, set_value)
    del get_value, set_value

if __name__ == "__main__":
    t = Test()
    print t.value
    t.value = 8
    print t.value
    try:
        t.get_value()
    except AttributeError:
        print "YEAH"
