- exact conversion of connected routes with nodes on ways should be
stable
- transitschedules can now be imported together with the related 
network in the import dialog
- stopIds will now be kept internally: during runtime the id refers to
osm relation and node; when writing out the initial id from the o
riginal schedule file (if it exists) will be recovered 
- ways that are used in connected routes will now be converted prior to
converting the route 
- nodes on ways that represent stops will be kept even without "keep
paths" option
- the convertdefaults for different transit modes can be adjusted in the 
osmconvertdefaults dialog (tram, subway, light_rail, bus)
