Updated Gitignore to ignore Work folder.  Debugged ENoC.

sr_packet requires a typedef that doesn't exist.  I commented it out in
vlog.

Commented out arbiter compiles, they are now compiled in the LIB
directory.

Added ENoC and Lib to the compile list

Changed timestamp to 29:0 from 31 in net_emulation and packet_sink to
match with packet_source.  Will raise issue.

Commented out wave_spec.do as it doesn't exist.  Will raise issue.
