Support explicit option to load lib jars via javaSettings or classPath

[cfsimplicity]

Make it easier to bypass JavaLoader or osgi as the default java loading mechanisms (for ACF and Lucee respectively) by specifying "javaSettings" or "classPath". For example:

spreadsheet = new spreadsheetCFML.Spreadsheet( loadJavaClassesUsing="javaSettings" )

NOTE: overriding the defaults may result in class loading problems.

Also, add the loadJavaClassesUsing value to the info returned by getEnvironment()
