New Features: -TCP/IP Updated network stack -Ping (usage ping >ip<) does 4 8 byte echo pings to the inputted IP. -DNS Grabs the IP address from a domain name (Broken) -HTTPGET Gets http from a site (broken aswell lol) Bug fix: Moved the cmd apps out of the ISR so the system wouldn't hang on a ping or while trying to get DNS info.
