Loads of new features & fixes.

- Added: pour function directly into Iterable which allows to collect
all elements in the Iterable directly.
- Added: The new ToArray method from Java9 and newer into the library.
Using a functional interface. (Just a backport)
- Changed: Reworked how the Map Builder functions are created. They are
now in a SubClass that moves them out of the way. Less Clutter. (This
might break things if that was used before)
- Added: Map Builder that allows now to Build Maps like Guava
ImmutableMaps can be build. Note: This has a slight performance
overhead.
- Added: Unmodifiable and Synchronize wrapper functions direclty into
Collection Interfaces. This is mostly a quality of life thing.
- Added: Unmodifiable and Synchronized Wrapper Collections can now be
cloned. They clone the underlying map which doesn't break functionality.
(Had a usecase for it)
- Added: A boxed putAll array variant.
- Fixed: EnumMaps didn't keep track of their size and now got proper
care and implementations as needed. There might be more work required
but at least the core functionality is now up to date.
