Fixed DataConstants.
Added SystemUtils.isNDKSupported with special case for GoogleTV.
Added ant-contrib-1.0b3.jar.
Added build.xml that allows to remove native code when -Dndk=false is supplied. This is necessary for GoogleTV without NDK support (< 4.2.2).
Updated native libraries (built with ndk r8b).
Made ndk build through ant multi-threaded.
Updated .classpath for ADT 22.
