Pedro J. Estébanez d46e246d0f Rework warning levels
Now you have: extra, all (the default), moderate, no.
The old 'yes' option is still supported, but a warning will be printed and 'all' will be assumed.

The different options will translate to the following:

MSVC:
extra -> /Wall (implies /W4)
all -> /W3 + disable non-essential (*)
moderate -> /W2 + disable non-essential (*)
no -> /w

GCC/Clang:
extra -> -Wall -Wextra
all -> -Wall
moderate -> -Wall -Wno-unused
no -> -w

* = Truncations, narrowing conversions...: /wd4267 /wd4244 /wd4305 /wd4800
