Initial casting implementation

Explicit casts can be performed with the syntax 'cast<type>(input)'
and implicit casts can be performed with the syntax 'cast(input)'
where the output type is determined by inference.

To prevent casting shenanigans we only allow casting of primitive
types and of types to themselves (essentially creating a copy).

/* This example demonstrates:
- Synchronous channels can span the network if created by pairs of `connector_add_net_port` calls,
	each binding a port to the same address, with complementary polarities.
- Ports created this way have two notions of polarity:
	- (port) Polarity in {Putter, Getter}:
		- Putter => resulting port can `connector_put`,
		- Getter => resulting port can `connector_get`,
	- Endpoint Polarity in {Active, Passive}:
		- Passive => underlying transport socket will `bind` to the given address,
		- Active  => underlying transport socket will `connect` to the given address,
