Made MemberCollection mutable

due to poor performance.
Incremented patch version

in order to indicate that making MemberCollection mutable is a fix,
which is because of poor performance. This change causes a breaking
change, removing the protected constructor, but as it is less
posibility that a user depends on the constructor, this is treated as
the fix.
