Start way check added

[afischerdev]

This is the answer on the issues #600 and #682.

The idea is to place a definition for excludes highways in the profile.
This is scanned at routing start and an array is created with the index of the lookup entry and the lookup value.
The array is then used to exclude the way from the routing.

The test server is prepared for using this feature.
You have to assign a new global rule in the profile - there is no entry for this feature in the profiles at the moment.

assign   check_start_way          = true   # %check_start_way% | Activate a test for the starting way | boolean | noStartWay=route,ferry;highway,motorway;highway,motorway_link

As you see the comment part of the assign has in this case an array with 4 entries - please note, the web client can not check that at the moment, so you don't see the assigned entry in the option window (I guess, some of the RegEx in Profile.js should be changed).
The fourth part of the array contains the excluded entries.

noStartWay= - a fix constant for this new feature
route,ferry - entry for route=ferry
; - more entries comes here
