Fixed bug where only one of multiple source header directives with the same source header definition would be recognized. The fix was to improve the comparator function for HeaderFinderPattern so that it included context. Prior to that only one source header definition would be recognized because the ordinal is always 0 for source headers. As a result, only the first context could be registered.
Refactored HeaderFinder::CheckContent() to improve the coding style and make use of a switch().
Corrected a bug in HeaderFinder::CheckContent that would allow a header forced source IP to be set multiple times. Now it will only be set when the first event where all of the conditions are satisfied. Bug was that the test that the source had already been set was looking at the source IP which is actually never set until the actual message scan begins (after header directives have already been evaluated).
Changed SNFMulti revision to 16.
