TCRT_Test updated for new output style

FieldTest_File:
- Beginning now checks if the first line contains either “CPUC Tester
Beta” or “CPUC Traceroute Beta”
- moved around some variable outputs in __str__

TCRT_Test:
- removed Ping class
- Hop class is now simpler (contains HopNum, RTT, RouterName, RouterIP,
and _Timeout
- altered some outputs in TCRT_Test
- removed some unnecessary functions in TCRT_Test

moved test_parser to scripts (I may be using this more often)
