Updated RTI & POI models to parse updated RTI responses

RTIModel now also determines if a piece of RTI identifies a late running
service.
Updated to represent multiple RTI & Styling train RTI
Styling train RTI
POI detail can now accept params to specify a specific RTI
Cleaned up detailView and added alternateRTI support
Minor template changes
Parse today view RTI correctly

Removed call to getRTI
Shuffled around templates to bring RTI type into the rti box
Code style
Only fetch a POI for today card if we have geo data
Allow exactly on the error margin

This just helps me out with the geolocator firefox addon
Styling for RTI
Separate View for each RTI type

Hopefully this is an improvement, will try something similar with models
too. Perhaps it's possible to use dynamic calls to require() for a
similar effect.
rail-departures and rail-arrivals using the same view
Place all RTIModels onto one object based on type
Slight styling tweaks
RTIModel -> RTIModels, RTIView -> RTIViews

Now these present multiple types of RTI it makes sense to rename the
files.
