Deletion of Martin Porter

Comment: Clear pass of #C1 for his multiple highly cited papers (six pubs with over 100 cites each in Google scholar, not counting the repeated entries for his 5000+-citation work) and for plenty of third-party coverage of his stemmer. Also a likely pass of #C2 for the Strix award
