Assorted bug fixes

- If SctProcessNode ran into a timeout, its action data wa sdeleted. If data came
  later, this caused SICS to crash. This is now fixed
- sget leaked connections under certain circumstances
- Cosmetic fix to hipadaba.c
- yet another chnage to the TRICS file format in fourmess.c, now it prints magnetic field
  instead of the proton count
