Normalization rules should have different MSS values for either IPv4, or IPv4+IPv6.
Changed the protocol back to any, since I'm unsure if selecting TCP only means IPv4 TCP, since there is also only IPv6 selectable.

- Omitted Source Port in Firewall rules
- Added tip and note about dynamic WAN IP

- Changed Endpoint to Peer

* Some warnings and an example for clarity
Added a warning about overlapping networks for the LAN and Wireguard interfaces, as doing so will cause the clients not to be able to communicate with each other properly. Added an example to request another PD from your ISP, as ATT only hands out /64s and one will not be enough to subnet the networks properly.
* Clarification and briefness
Tried to add just enough information to clarify that it is a completely separated network that requires routing to reach the LAN interface.
Adding a specific warning regarding setting DNS servers in the WG road warrior how-to. Also fixing some formatting issues.
Adding instructions for IPv6 configuration in the WG selective routing how-to. Also fixing some formatting issues, and adding some other minor clarifications/explanations.
