[TASK] Make Permission class a BitSet instead of Enumeration

The Permission class unnecessarily had been implemented as
Enumeration although the features of the Enumeration base
class hadn't been used.

As the Permission class only handles boolean flags, it is
now implemented as bit set, which improves the performance
in comparison to Enumeration classes.
