Verbose Bug fix and pattern loading optimization

Browse Source 
Verbose flag was not proceeding with the next scan due to !found being set.  Added a check to see if it is verbose when it decides to do the next scan.

Patterns should be loaded once and only once.  The files aren't large so not a problem with memory, however it might impact performance if we are loading the same 3 files ever time we scan a file.
