The defaults for the console plugin does not log calls to the native logger

in logger-startup.js:
logger.useConsole(true);

If you set it to false, it logs to both. We want it to log to the native logger by default.

Fix:
1. Remove logger-startup.js
2. In logger.js, set UseConsole to false as a default
3. Update plugin.xml if necessary

Typo in logger.js:
1. console.__usingCordovaLogger is never set anywhere else, it should be console.useLogger()
