(svn r17433) -Codechange: Store cumulated inflation in savegame and compute all prices from that instead of storing all prices separately.
Note: Savegame conversion computes the inflation from max loan. Prices from modified savegames will get lost. TTO savegames will also behave slightly different.
-Change: NewGRF price modifiers now take effect everytime when loading NewGRFs instead of once on gamestart.

(svn r17113) -Change [FS#265][FS#2094][FS#2589]: apply the subsidy when subsidy's destination is in station's catchment area and cargo packets originate from subsidy's source
-Change [FS#1134]: subsidies aren't bound to stations after awarding anymore, they still apply to town or industry, no matter what station is used for loading and unloading. Awarded subsidies from older savegames are lost
-Change [NoAI]: due to these changes, AISubsidy::GetSource and AISubsidy::GetDestination now return STATION_INVALID for awarded subsidies

(svn r17058) -Codechange: magic numbers removal.
Two values used intead of just one, as it gives more possibilities to those who dare...

(svn r16694) -Fix [FS#2995] (rgradual loading, rnewindustries): only pay for whatever has been actually unloaded and perform the payment when unloading has finished. This fixes, amongst others:
* cheating by starting to unload and after getting paid rushing to the depot to get sold (or unloading, loading and getting paid again for the remainder)
* cargo being dropped onto a station at the moment a stockpiling industry doesn't accept it anymore
* industries getting cargo that has not been unloaded yet and subsequently dumping it back on the station in one go
Note: you will now get paid after the unloading has finished, so you'll have to wait a bit longer for 'your' money.

(svn r15027) -Merge: tomatos and bananas left to be, here is NoAI for all to see.
NoAI is an API (a framework) to build your own AIs in. See:
http://wiki.openttd.org/wiki/index.php/AI:Main_Page
With many thanks to:
- glx and Rubidium for their syncing, feedback and hard work
- Yexo for his feedback, patches, and AIs which tested the system very deep
- Morloth for his feedback and patches
- TJIP for hosting a challenge which kept NoAI on track
- All AI authors for testing our AI API, and all other people who helped in one way or another
-Remove: all old AIs and their cheats/hacks

(svn r14705) -Fix [FS#2460]: First transfer the whole load of a vehicle chain to industries before triggering any processing.
This reduces callback usage and resolves critical rounding errors when using input-cargo-multipliers instead of production callbacks.

(svn r14672) -Fix [FS#2444]: Property 7 and callback 12 were broken for aircraft.
Now callback 12 is properly called also for 'mail'.
If the callback is not used, 'mail' uses 1/4 of property 7 (rounded up).

(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 r14105) -Fix: Some typos that are more grammatical errors, as it seems.

I've added a little fix on currency.cpp too, why not :)

(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.
