Push in Tuakiri work on log parsing scripts

Hi,

I have made quite a bit of work on the log parsing scripts.  We have been keeping this in our Tuakiri clone of the FR 1.2.x repo.

When porting this for FR 2.x (just moving the scripts over, no code change needed for different FR versions), I thought I should contribute this upstream - hence this pull request.

Cheers,
Vlad
