updates to rlogin

Hi, this patch:
- uses value_string for control message field
- doesn't use a single global time value to mark start of all conversations!
- corrects client-user-name, server-user-name order in initial user-info
message
- adds data (text input/output) into the protocol tree
- makes lots more things filterable
- improves info column text (always calls rlogin_display() now)
- cleans up some whitespace
