Martin CarlbergandGitHub 1c866931f3 New: The compiler will now create warnings for variables that are never read (#2871) ...

This new warning adds a lot of warnings in the Cappuccino frameworks. I have turned off
the warning in the Jakefiles when compiling most of the Cappuccino frameworks. But it is
on as default for any user projects.

So there is also a new feature to turn off/on warnings as a compiler flag.

These flags are (all flags are on as default):
-Wunused-but-set-variable                    Warning when a local variable is never read.
-Wshadow-ivar                                Warning when a local variable is shadowing an instance variable for the class.
-Wcreate-global-inside-function-or-method    Warning when creating a global variable inside a function or method.
-Wunknown-class-or-global                    Warning when a class or global variable is not known.
-Wunknown-ivar-type                          Warning when the type for an instance variable is not known.

To turn off a flag add a 'no-' prefix. Example: -Wno-unused-but-set-variable

For an example how to use it in a Jakefile please look at the Jakefiles in this commit.
