Set per-field values for the maximum length of multi-token matches

[Gray-Davidson-00]

Hugh, I added a dictionary to contain all five max_token_count values. I estimated liberal defaults for all 5. The correct value for max_token_count is employed in label_tokens below. This bypasses the work you did to pass max_token_count as an argument but I couldn't easily figure out how to pass in a dictionary of values. In any case, modifying the dictionary at the top of the file should do what we want here.

Thank you! Once you take out the hardcoded check for advertiser it's all done. (as of right now we skip the value we get out of the dictionary if it's not an advertiser)
