(svn r11760) -Codechange: unify the way how other end of a tunnel/bridge is determined at some places
-Fix: adding road/tram to tram/road bridge was cheaper by one tile

(svn r11523) -Codechange: Move the CHANCE macros to core/random_func.cpp cause they depend on Random()
-Codechange: Convert the CHANCE macros to functions and rename them fitting to the naming style

(svn r11399) -Feature(ette): transparency settings can now be saved and thus remembered.
-Codechange: Wrap all transparency settings in accessors, hiding the implementation
-Change: Clicking "transparent building" menu will toggle Houses And Trees only. The other options can be used in the transparency gui.
Initial patch by Smatz (FS#1349), with some rework by BigBB and your humble servant.

(svn r11276) -Codechange: be more consistent with naming of some accessors.
-Fix: make sure canals are never owned by water. Based on a patch by boekabart.

(svn r11197) -Fix: It is not useful to reset the override of an entity every time a new grf file is been submitted.
Since newhouses showed the way to newindustries(meaning I copied/adapted a lot of code and processes from it), the behaviour was there for newhouses too.

(svn r11188) -Codechange: rewrite of the town action related code (remove some of the magic).
-Feature: possibility to disable exclusive rights and giving money. Both by skidd13.

(svn r11005) -Codechange: move the tiletype specific terraforming checks to the functions for those tile types.
-Codechange: barren the rail grounds on terraforming.

(svn r10323) -Codechange: reference company name, number and player (president) name
by index

(svn r10167) -Codechange: Change the flagging system of grf loaded feature from a bitset to a bool evaluation.
Like easier to read and faster to evaluate :)

(svn r9850) -Codechange: Introduction of the Override/Substitute manager. Currently only used for newhouses.
Basically, it is more a gathering of IDs from grf files and ingame data.

(svn r9779) -Feature: Add the possiblity to choose different road patterns for towns to use.
Possible patterns are :
No Road (not available in scenario editor)
Original (for the nostalgics)
Better Roads (same as original, but based on distance of 2 tiles instead of one)
2x2 grids
3x3 grids
Patch by skiddl13

(svn r9762) -Feature: Two new difficulty settings : Very low number of towns and very low number of industries
Based on FS#289, by pitt2

(svn r9722) -Documentation: Document some functions of town_cmd.cpp. Loosely based on work from TheJosh
More to come.

(svn r9667) -Feature: Add the concept of cities. A (configurable) proportion of towns can
start off larger, and will grow twice as quickly as other towns. They can also
be placed specifically in the scenario editor. Thanks to TheJosh for the
initial patch and the idea.

(svn r9613) -Feature: Make it possible to have some control over the town growth. The
default rate is TTD's original rate, and to approximate OpenTTD's previous
behaviour the rate should be set to "Fast" or "Very Fast". Town growth can be
switched off entirely, and if so, buildings will not be rebuilt. It is also
possible to specify a proportion of towns that grow twice as fast as the
others.

(svn r9371) -Feature: Add support for variable snow lines in the arctic climate, supplied
by newgrf files. When this is enabled forests cannot be built below the highest
snow line, and farms can't be built above it. Houses still use the
_opt.snow_line so they are all consistent, so to make them respect the snowline
you may want to use some newhouses features as well.

(svn r9367) -Fix (r9315): If a new house doesn't have a corresponding action 3, the
graphics for the substitute (original) house should be drawn instead.

(svn r9315) -Merge: The newhouses branch. With this merge comes almost complete support for
the newhouses grf specs, so all newhouses grfs will be playable in the game.

Many thanks to everyone who contributed code and ideas, and all the testers
who found things we missed.

(svn r8875) -Fix

Remove unnecessary EnsureNoVehicle() checks because they are
- pointless per se (f.e. there are no vehicles on house tiles)
- done again (f.e. using CMD_LANDSCAPE_CLEAR just a few lines later)
