Changes the weight quantification to exclude comparisons of a message with itself. Previous to this change every activity by a user that met the criteria for that network type would be included in the self edge weight - eg. every retweet would be a co-retweet with itself.
The previous behaviour is undesirable because it significantly inflates the weight of self edges according to the account activity - this change gives a more accurate representation of the self edge weight, allowing easier detection of things like reply spam from a single account. I think the earlier behaviour is more of an oversight because we focused more on coordination across accounts rather than the self similarity.
