Provide IDnpTimeSource in Java and C# bindings.

[emgre]

Fix #353.

• Adds the Now method of IDnpTimeSource to the Java and C# bindings.
• All the outstation update methods now takes a DNPTime with a timestamp quality. This is mainly used when reporting using CTO (g51v1 when synchronized, g51v2 when unsynchronized).
• This introduces breaking changes and won't be merged into the 2.x branch for now.
