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

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.

Codechange: Use override specifer for overriding member declarations

This is a C++11 feature that allows the compiler to check that a virtual
member declaration overrides a base-class member with the same signature.

Also src/blitter/32bpp_anim_sse4.hpp +38 is no longer erroneously marked
as virtual despite being a template.

(svn r27928) -Fix: [NewGRF] While executing random triggers, var 5F should include the new triggers.
-Fix: [NewGRF] Reset used random triggers only after all A123 chains have been resolved, so that all RA2 in all chains can test the shard triggers. This also includes multiple RA2 in the same A123 chain.
-Fix: [NewGRF] Industry random triggers are stored per tile, even when randomising the shared random bits of the parent industry.

(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 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.
