/**
* Utility method to check if JSF 2.0 Facelets should be disabled. If it's not explicitly disabled
* by the context init parameter, then check the version of the WEB-INF/faces-config.xml document.
* If the version is less than 2.0, then override the default value for the context init parameter
* so that other parts of the system that use that config option will know it has been disabled.
*
* <p>NOTE: Since this method overrides a configuration value, it should be called before *any*
* document parsing is performed the configuration value may be queried by the <code>ConfigParser
* </code>s.
*
* @param webconfig configuration for this application
* @param facesConfigInfo object representing WEB-INF/faces-config.xml
* @return <code>true</code> if Facelets should be disabled
