assert keyword do not work

[Fogapod]

I saw this issue first and decided to check if this problem occurs in other kivy python implementations on Android. Assert did not work for me in apps builded with various versions of p4a (from old toolchain to 0.6.0)
Syntax assert False is ignored in any kivy app on Android (not sure for python3 builds though)
I assume the the problem is somewhere in the python build process

Because p4a ship compiled version (optimized?) of Python bytecode (-OO). This removes the assert and code behind __debug__. You can consider it as "release" code shipped into the APK.

Now that you mention it, i guess it would be nice to do that only for the actual release, and not debug mode.

That would make sense to me. I'm not sure the -OO affects the size much anyway.

I made a PR at #1221 that should fix this, but haven't tested it yet other than to make sure the compiling works.
