Added label to splitted roads/areas
Commited start of linker tests

Idea is that we have exports of OSM where public transport stop linker
had many errors in the past.
With this exports we define on which paths linker should link stops.
And then it is much easier to write new linker.
Cleaned and rewritten output to geojson in linker Tests
Now we look for walking paths then for service paths in LinkFixes
Moved StreetType
Added GUI for LinkerTests to Vizualizer

You can add transitStop and edge which should be connected to it.
Import, export and editing aren't finished yet.
Added more logic to Linker GUI

You can open a file, edit transit-> edge connection. And add updated
connection to the list. Highlighting of vertex and edge also works.
Problem is with enabling/disabling buttons
Fixed problem with buttons enabling

addInterval was called before vertex/edge indexes were set.
Opening editing adding and saving works

Problem is that when highlighting and zooming to transit stops is
clicked. Selecting a vertex is no longer possible.
Should fix strange toolbar sizing problem

Sometimes right toolbar lengthens over graph view and under left
toolbar.
Written testing part for Linker Tests
Added Maribor test files for Linker test
Added ability to mark stations as checked
Saved transit stops are sorted according to name now
More readable stop names on linker test error reports
Junit test was checking wrong text for linker tests
Number of succesfull connections is shown
Added saved transit connections
Added some comments to tests
