- Fixed a bug within `dhcp.pas` - `processPacket_OFFER` in which the client was responding with the client IP value within the DHCP header was incorrectly being filled out with the IP being requested & this value was then being used within the REQUESTED_IP_ADDRESS option. Corrected this to fill out the client IP with the currently configured IP, which will be NULL (0.0.0.0) on boot, and whatever is issued thereafter.
- Cascaded the change to use the currently configured IP as opposed to a NULL IP to any other functions that were calling `copyIPv4(@NULL_IP[0], @packetCtx^.IP.Source[0])`.
- Allowed `processPacket_OFFER` to process packets addressed to the BROADCAST MAC (WHY COULDN'T IT DO THIS ALREADY?!).
Added the apache license to all source files, accounting for authors. Also added a license.md containing the apache license + contributors.md listing all contributors.
