[TIMOB-17369] CLI: Auto-escape quotes in tiapp.xml

Resolves https://jira.appcelerator.org/browse/TIMOB-17369
Unfortunately, can't do this. The `cli.tiapp.description` is used by too many places including analytics and detecting if the tiapp.xml changed.

You should be escaping the description where it's being used. This means you should update `android/templates/build/AppInfo.java`.

Also, there's no need to escape single quotes. You should only need to escape double quotes.
