Updated project to clear up all compiler warnings when building.

- For all 3rd party files which we prefixed ourselves, I have just ignored all the warnings as changing 3rd party code is never recommended.

- For all of our own codes warnings,  I have gone through and made the necessary changes to fix the warnings.
Refactored ApigeeCompositeConfiguration to ApigeeApp and ApigeeMonitorSettings to ApigeeMonitoringSettings
Updated sample projects to more easily run sample apps.  Also updated the sample projects ReadMe file.
