Added in a config class to access main config properly and now can be called from anywhere in the code by creating a instance.

Re-coded migratecfg, vast improvements made and code cleanup of unrequired checks.

Fixed numerous small bugs throughout nzbToMedia including possible calls to variables that may not have been created do to conditional statements.
Added a chcek for sample cfg file and if not found it copies the .cfg to .sample and runs migratecfg so it can check the cfg over and make sure its not missing any sections, options, or values and migrates old cfg style to new cfg style.
Added exception handling for bad files or missing files
Fixed bug in new config class that was preventing it from not creating a instance based on our conditional checks.
