Added getters and setters to NDK, Moved NDK ndk field from NdkBuildMojo
to AbstractAndroidMojo, Added ndk.getPath() (the
<ndk><path></path></ndk>) to getAndroidNdk implementation, changed so
that if a command line parameter android.ndkpath is available, it gets
picked first, then if <ndk><path></path></ndk> is available it gets
picked, then if an ANDROID_NDK_HOME env var is available, it gets picked
- I also changed it in javadocs.
