fix IHttpService implant

corrects the error and disables the wraper function
a little more Ruby-like helpers
fix returns for arrays of scanissues and hrr

BurpSuite methods that return an array of IScanIssue or IHttpRequestResponse objects now all return the proper ScanIssuesList or HttpRequestResponseList object.
This will be reversed in 2.0 so all functions simply return the array of IScanIssue or IHttpRequestResponse objects.
