Show train delays, cancellations etc in the timetravel page in red color

[krnekhelesh]

Just in like other pages, we should show delays in red color to indicate that it will affect the user's journey.

This issue stems from 2 problems that I was able to observe,

• The text format in Ubuntu Touch is not set RichText and as such the color tag defined in the 9292 parser is ignored. This is quite easy to fix.
• In some parsers like mobilebahnede.cpp, munich_efa.cpp, I don't see color tags being defined for late arrivals. I am not sure why this is the case. Either way, is it safe to assume that if the text !== qsTr("On-Time") it is a delay and mark it in red?

I don't really like the color defined in the backend, i don't remember the issue number but we discussed maybe exposing some info in additional fields.

I think realtime statistics could be such an additional field.

Values could be: null = no realtime data 0 = on-time > 0 delay in minutes

This field should be available for timetable and journey. After that the gui can handle how and in which colors the data will be presented.

Edit: maybe even two fields, one for the status and one with textual info about the delay itself (if available)
