Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

(svn r25841) -Codechange: Use NUM_AIRPORTTILES_PER_GRF instead of NUM_AIRPORTTILES to properly distinguish limits per NewGRF and limits of the pool.
-Change: [NewGRF] Lower the limit of airport tile types per NewGRF from 256 to 255 to prevent usage of ID 0xFF in Action3, and thus allowing it to become an extended byte somewhen.

(svn r19353) -Codechange: use static objects for the airport statemachines instead of new/delete at the start/end of the game
-Codechange: store the fta in AirportSpec

(svn r16614) -Codechange: Make the airport min/max available year a property of the Airport class.
-Change: rename station.always_small_airport to station.never_expire_airports to make it more future-proof

(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 r8767) -Fix

-Codechange: Do not hardcode the catchment radius of airports, but hold the information in AirportFTAClass
-Fix (r979): The default AI tested possible airport locations with a fixed catchment radius instead of the radius of the to be built airport

(svn r8748) -Fix

-Codechange: Do not hardcode the airports with a short airstrip anymore, but make it a flag in AirportFTAClass

(svn r8747) -Fix

-Codechange: Make the encoding of accepted aircraft types of airports a bit more sensible and move the enum into struct AirportFTAClass

(svn r8743) -Fix

-Codechange: Add a Z adjustment attribute for helicopter pads to AirportFTAClass to get rid of some special cases for oilrigs and heliports

(svn r8582) -Fix

Reorder the attributes of some structs to reduce their size

(svn r8570) -Fix

Add a regular constructor and destructor to AirportFTAClass

(svn r8559) -Fix

-Codechange: Put the airport movement data into struct AirportFTAClass

(svn r8305) -Codechange: defining 'static const' in a header is a bit weird.
Above that, wince-gcc gave "unused variable" on every file which included airport.h... pretty annoying ;)

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
