Created new branch "wuerzburg" that contains code changes which shall
only be conducted for the wuerzburg-exercise:

- put a copy of transportation-widget into the top level view of the
breadcrumb-stack-navigation component

- now response phases without chart content are hidden in
breadcrumb-stack-navigation component

- the KPIs descriptions have been updated (according to BRK feedback),
but the values (from icmm) are still replaced by mock-up values
- updated wirecloudcontroller: now reading available kpi items
(currently timeline widget specific) and logging them
Added a proprietary computation of following kpi values:

-1: Time until last patient is transported to the hospital
-2: Time until red patients are away from the incident scene
-3a: Ratio of medical responders per patient
-4a: Time until all patients are pretriaged
-4b: Time until all patients are triaged
Added a proprietary computation of following kpi values:

-6a: Number of application of basic measures on scene
-6b: Patient / mime assessment of basic measures
Added a another proprietary calculation for kpi4a and kpi4b, but
disabled it via comments:

-4a: Time until all patients are pretriaged
-4b: Time until all patients are triaged
Fixed problem with colors in care measures widget.
- updated calculation of kpi3a and kpi6a according to new patient/care
measures data structure

- reading step minutes properties for diagrams from wirecloud
A worldstates timeline data now is identified by category key
'capture_data' and 'indicator-value'
- Changed some textlabels (in navigation list and chart legend): renamed
„Transportation of patients“ into „Start of Evacuation of Patients”

- changed calculation of kpi1 (Time until last patient is transported to
the hospital) and kpi2 (Time until red patients are away from the
incident scene): now using "Reference Time" instead of "Transportation
Start Time"
Merge branch 'wuerzburg' into dev
