NewGRF Meta Language

With NML 0.4 we change some of its foundations, it now is written in python3 and requires python 3.2 or newer. Requirements are:

New warnings about and flags for realsprites: (NO)ALPHA, (NO)WHITE and (NO)ANIM. See explanation in realsprite page.
Rigerous caching of real sprites. This improves encoding speed a lot on subsequent runs, especially for NewGRFs with many real sprites, more so for 32bpp
Statistics on the NewGRF on used IDs for vehicles, houses, etc as well as available switches, parameters etc

Feature: [NewGRF] create_effect and effect_spawn_model
Feature: [NewGRF] EFFECT_SPRITE_NONE constant for create_effect callback
Feature: [NewGRF] support for OTTD_RECOLOUR action5 sprite(s)
Feature: [NewGRF] Support for Latin translations
Feature: [NewGRF] Variable to test for enabled wagon speed limits. (issue #6474)
Feature: [NewGRF] Warn about usage of animation and semi-transparent colours, and add spriteset flags to enable/disable the checks. (issue #1085)

-Note to package maintainers:
-    Dependency change: python 3.2+
-    Dependency change: preferably use pillow for python3 as imaging library instead of PIL.
-    Build requirement change (optional): c compiler needed to build the optional cython module for grf encoding (nml/_lz77.c). It's an optional speed improvement over the python-only implementation.
