VERSION: Increment to 11.14
FIX: Occasional crash on changing seasons
FIX: Integer overflow in the path explorer causing routing anomalies
NOTE: This is only a partial fix. A full fix will require changing all journey times from 16 bit to 32 bit integers, whcih is best left to a major version.
FIX: Apply previous fix properly
FIX: Prevent perverse routing decisions if actual routes are > 65,335 10ths of a minute as far as possible.
FIX: Did not always properly detect anomalous point to point journey timings with the result that inaccurate data (sometimes of zero time routes) were saved.
CODE: Minor whitespace/comment changes.
CHANGE: Passengers, mail and goods are now loaded on vehicles in the order in which they arrived at a stop (as in a 'bus queue).
CHANGE: Improve performance of last change
CHANGE: Passengers' maximum waiting time is no longer limited to thrice their estimated journey time, and behaves like the waiting time of all other types of load.
VERSION: Increment to 11.15 development build
FIX: Incorrect revision number.
Merge branch 'master' into 11.x

Conflicts:
	simversion.h
FIX: Set the default minimum runway length for paksets not compatible with the minimum runway length feature to 10m rather than to 0m, as a length of 0m implies VTOL.
FIX: Power stations in cities acted as consumers of electricity as well as producers.
FIX: Skip multiple substation distribution code where there is only one substation in a city.
CHANGE: Upgrade dr_rdpng.cc to the latest version from standard.
CHANGE: Increase the default rolling resistance of tramways and roads according to historical research
FIX: Makeobj project files were not configured correctly
FIX: Maximum speed and weight were not displayed in the tooltip for ways with prohibitive way constraints
FIX: Crash on reversing in some cases
CHANGE: Further increase of default rolling resistance for trams (4x that of rail)
FIX: Errors in calculating routes with long-block signals and, in some cases, choose signals
