Instead, have the build script copy do the equivalent logic on each
build.
Advantages:
- Scripts run much faster
- No more duplicate CordovaLib entries in project.properties
- Building is more independent from create/update script (more robust)
Uses heuristics:
- Adds javac to PATH based on default install paths on Windows
- Adds javac to PATH based on JAVA_HOME
- Adds android and adb to PATH based on ANDROID_HOME
- Sets ANDROID_HOME based on location of "android"
This prevents the 'cordova build android' process from blowing up on this step if you assign the GDK as the target and want to rebuild via the CLI.

Since cordova-cli calls the check_req library run() method, we do not
want to always console.log on success in there (not usually a useful side
effect).
This eliminates the use of shelljs.exec's sync mode, which is the source
of the filehandle leaks that can cause EMFILE on OSX, and are
CPU-intensive everywhere.
Tested locally, needs poking before it gets released.
