Use print() and byte strings to make the code compatible with Python 3,
while also keeping it compatible with Python 2 (>= 2.6, at least).
Closes https://github.com/wxWidgets/wxWidgets/pull/1348
Wrong multiplier was used for the most significant byte. Fix it even though it
doesn't risk to be a problem in practice as the images of such gigantic size
would surely break some limit anyhow.

When a PNG image exists in several sizes it makes sense to use its size as a
suffix to distinguish the different versions, so update the png2c script to
optionally allow to do this.
Current implementation simply checks the PNG header directly to avoid any
extra dependencies.

Tango icon files often have dashes in their names so accept them in png2c
conversion script and simply replace them with underscores to form a C
identifier for the array containing the image data.

Use a simple implementation working under all OS X versions, including 10.4
which doesn't have standard system images for the close button.
Added the images themselves under art/osx and png2c.py helper script to
convert them to a form used in C++ code.
