This reverts the house picking/placing patch back to v2.
This is to fix house placement/town growth desync issues introduced in v4.
# Conflicts:

Remove global on-off setting.
Add button to timetable GUI.
Add company setting to control default for new vehicles.
Fix automate, start date, change time and autofill buttons
being shown enabled for other companies' vehicles.
* Revert breakdown_chance to (mostly) its original behaviour.
* Create a new breakdown_chance_factor to hold breakdown_chance
from improved breakdowns logic.
* Revert airport crash probabilities back to original behaviour, with
modified behaviour only during emergency landings.
* Low power breakdowns now only reduce the power of the engine which
has broken down.
* Low power breakdowns no longer reduce speed directly.
* Add callback function to run whenever improved breakdowns setting
is changed. Reset breakdown_chance_factor where required.
* More whitespace/formatting...
Savegame format change for link graph jobs.
Change link graph scheduler to support more than one operation
per day, on _date_fract ticks other than SPAWN_JOIN_TICK.
Probability of placing an arctic tree is now an exponential decay
function of height distance from the snow line, instead of the previous
50% blocks.
This results in a more gradual thinning out of arctic trees in
each direction.
The algorithm is: p = exp(-3 * distance / range_setting),
using a rather crude approximation of the exponential function.
The no_trees_on_this_level setting is not really useful, and its
dual behaviour to disallow discrete height levels and turn on the
snow line behaviour is unintuitive.
Replace it with a simple on/off setting.
These correspond to versions from v2.1.108 and v2.1.147.
The oil rig airport type bug is fixed as of version 221.
The oil rig type has been moved, but this is not a problem as
the afterload code already remaps it to the correct value.
The cost scaling issue also seems to have been mostly fixed
as of version 221.
This is useful for loading settings from legacy/special versions,
where the corresponding setting is somewhere else and/or a PATX setting,
with duplicating all the info.
Use this to load SpringPP settings which have a corresponding setting.
