use -isystem instead of -I to include external libs - silence warnings
fix bug in Python for python <= 2.7.5 in Wformat=

https://bugzilla.redhat.com/show_bug.cgi?id=927358
use system includes for numpy & python

(-isystem, instead of -I)
use Wdeprecated
compile flags: Wreturn-type already in Wall
compile flag: Wunused

unused + more, but turn Wunused-parameter only to warnings for now
use Werror
add Wno-error=cpp because of Numpy warnings

\#warning
add std=c++11 compiler flag

in addition to linker flag already used in CMakeLists (in platform section)
CMake add section for #define preprocessor variables
revert: silencing Numpy deprecated warning

it caused more problems, but silence worked!
CMake provide compiler specific options

to set (incompatible) flags, etc.
be sensitive about std=c++11 flag

not supported by gcc4.6 -> must use std=c++0x (=older compatibility)
but c++0x is unknown to clang --> do not directly add to the CMAKE_CXXFLAGS_BASE
variable, but let cmake be smart about it.
use Werror only on GCC

Clang caused problems with W#warnings thrown by Numpy API
Updating to latest nupic.core.
