There are no dictionaries that sum up all possible conjugations, using a heuristics based normalizer would be more appropriate. There are nevertheless some good sources to start:
Contains lots of useful spelling issues, incl. british/american/canadian/australian http://grammarist.com/spelling Very useful http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences#Acronyms_and_abbreviations A handy list http://www.avko.org/free/reference/british-vs-american-spelling.html There are some more lists but it seems the other one's tab is no longer open!
