Checks a filename to see if it matches the specified wildcard matcher

The wildcard matcher uses the characters '?' and '*' to represent a
single or multiple wildcard characters.

@param filename  the filename to match on
@param wildcardMatcher  the wildcard string to match against
@param caseSensitivity  what case sensitivity rule to use, null means case-sensitive
@return true if the filename matches the wilcard string
