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

Codechange: Make SpriteType, CargoSortType, SourceType and ScriptType enum classes. (#10663)

This avoids a (soft) namespace conflict between the four ST_* enums.

Fix #9804: Only apply sprite_zoom_min setting when sprites available (#9988)

Only discard sprite zoom levels when a suitable higher zoom level is
defined in the same colour mode

This is to avoid placeholder or empty sprites being used, causing
visual artefacts

Feature: NewGRF callback profiling (#7868)

Adds a console command newgrf_profile to collect some profiling data about NewGRF action 2 callbacks and produce a CSV file.

(svn r10092) -Codechange: code-seperated the spriteloader and blitter from the rest of the code
-Add: make it possible to pick your own blitter (-b <blitter>, -h for overview)
-Add: added a new optimized 8bpp blitter (default, caches sprites of all zoom-levels)
-Add: added a debug 8bpp blitter and a very slow normal 8bpp blitter

(svn r10042) -Codechange: Replace hardcoded spritecache size with a configuration
option, sprite_cache_size. The default size is 2MB and the value can
range from 1 to 64MB. If you experience slow-downs when scrolling the
map, try increasing this setting.

(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.
