(svn r14735) -Codechange: remove a bit of bit-waste in the map array (without changing the map array) and make the CompanyIDs contiguous.
-Note: 15 should be enough for now... making it any more means adding more bytes to the map array and thus wasting more bits instead of reducing the bit waste.

(svn r14332) -Fix[FS#1885]: Balance the monthly random industry changes, by introducing a daily random industry change.
This will allow to perform more changes per month on big maps and less on smaller maps, while not overtaxing the IndustryMonthlyLoop process.
Thanks to frosch, for nice code ideas and rewrites

(svn r13256) -Codechange: merge the OPTS and PATS chuncks.
-Codechange: split the diff_custom variable.
-Feature: allow changing some of the diff_custom variables via the console in network games.

(svn r13251) -Codechange: rename _patches to _settings as that is more logic.
-Codechange: move all Settings into substructs of _settings in a way that they are logically grouped.

(svn r13226) -Feature: Allow to have more than only two airports per town. The number of airports is now controlled by the noise each of them generates, the distance from town's center and how tolerant the town is.
Initial concept : TTDPatch (moreairpots), Initial code : Pasky
Thanks to BigBB (help coding), Smatz Skidd13 and frosch for bugcatches and advices

(svn r12648) -Feature: allow four different non-stop types in a single game instead of two. The "TTDP compatible order" setting now only sets the default behaviour of new trains.
-Feature: allow three different load type in a single game instead of two. One can choose full load all and full load any instead of full load being governed by the "full load any" patch setting.

(svn r12293) -Feature: Ability to change aircraft speed factor, from so
called 'realistic' (matching other vehicles) (1/1) to original TTD
speed (1/4). Note this option defaults to original TTD speed.

(svn r12134) -Change: count the number of ticks a vehicle was running this day to calculate running cost
-Fix [FS#1739]: vehicle profit is now counted with 8bit fract, so it is now shown properly in the vehicle details window

(svn r12042) -Fix [FS#1676]: Reimplement how rivers and canals are stored in the map, allowing the sea/river/canal status to also be
stored for buoys, docks, locks and depots. All these are now allowed on rivers and removal of them will revert to the
original water type.

(svn r11822) -Codechange: Replaced fixed size custom name array. Names are now attached to their object directly and there is
no limit to the amount of names.
-Fix: NewGRF engines could not be renamed.

(svn r11244) -Fix: trees can now be planted on bare land without making it grassy (Csaboka)
-Fix: planting tree in desert doesn't make it grassy for the first tile-cycle (Csaboka)
-Fix: when a tree dies in desert, it no longer becomes a snowy tile for the first tile-cycle (Csaboka)

(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 r10541) -Fix [FS#1028]: cargo payment rates overflow.
-Fix: cargo payment rates diverge from cost rates making it impossible to make any profit after a certain number of years.
Both are solved by stopping the inflation after 170 years; there is absolutely no point in continueing the inflation after that as it only makes the game have overflows at some point that cannot be solved; using larger variables only delays the inevitable.
