As a product manager, I want to be able to understand how often disambiguated links are added to the encyclopedias so that we may understand the extent of the problem around unwanted disambiguated terms.

Acceptance criteria:

• Create a new schema for the data we'd like to collect. This tentatively would include:
  • The number of disambiguation links being added with the edit
  • The editor used to make the edit
  • The wiki the edit was made on
  • The page namespace
  • Possibly also the edit count and/or age of the account, to verify whether this is primarily an issue with new users
• Implement the EventLogging itself into EditPage.php (all edits go through this class, I believe), to log the relevant data when edits are saved.
