Show my vote history for a specific tag.
VoteTypeFilter is optional, but the UI forces you to at least throw a space in there. The filter is a case insensitive filter on the VoteType column so you can enter 'up', 'accepted' or 'bounty' for example to filter those. For a full list of vote types see http://data.stackexchange.com/stackoverflow/query/73707/list-of-all-votetypes.
