Task/435 loglib lmi et al

### Description
Pretty much everything for the log migration.
  o LM_I for start/stop transaction.
  o IP and port in start/stop messages.
  o N/A instead of 'unset'.
  o Long names for levels
  o renamed the logfile from Log to .log
  o time zone in log line
  o 2 hour bug fixed
  o milliseconds inside TIME - one record less in the log line

What's still missing is the alarms, LM_W and LM_E:s with 'special' strings in the msg part.

We'll have to look into it.
FYI
LM_M is just a message that is not filtered with any CLI options.
LM_F is just like LM_M, but 'forced', thought for 'forced verbose level'.
