[Open-transport] SBB - HAFAS --> GTFS Conversion

The HAFAS-Converter for the SBB feed is a fork of the converter 
developed by Stefan Wehrmeyer a year ago. We fixed some issues with the 
HAFAS-format (many byte-positions were incorrect), changed the 
generation of trip and route ids and did some other minor modifications. 
Additionally, we added auto-generated colors to the feed that resemble 
the "official" SBB colors.

However, the converter still is in an alpha stadium and has several 
known issues. As Stefan pointed out correctly, frequency-based HAFAS 
connections are skipped and, most importantly, each HAFAS-trip maps to a 
GTFS trip _and_ a GTFS route. This is because we could not yet find a 
reliable mechanism to create "real" GTFS routes without creating id 

We did not yet check the converter against the HAFAS feed published by 
SBB a few days ago, but we will do so this week (I think tomorrow). The 
whole script is still work-in-progress and will be heavily updated by us 
during the next days.

First of all great work, no flame intended.

But some parts of the conversion are not done properly. For example
frequency based services have been ignored. There are some other things
fishy things that should be checked.
