Will test and de-WiP tomorrow.\r\n\r\nScent calculations in `game.cpp` involve using public map functions that all do bounds checks and re-get the submap every single time. There are 4 bounds checks per every single tile (`has_flag`, `veh_at`, `has_flag_ter_or_furn`, `field_at`) and every tile that contains a vehicle goes through all parts of this vehicle to find obstacles. Twice.\r\nSo a 10x10 DeathRoller that has a total of 200 parts will cause a total of `2*200*100` checks per turn.\r\n\r\nIn this PR I move the flag checking, vehicle checking and creating scent over slime to private map functions.\r\nIn order not to duplicate the submap lookup code, I created a neat templated function that invokes a functor on submap tiles, intelligently going through submaps in the area rather than re-getting them each time. The function also clips area to map bounds to avoid doing bounds checks.\r\nIt could be easily re-used to speed up some other sections of code, like NPCs looking for items, creating a cache of watery tiles (to speed up field processing when there are many fields), player radiant temperature function (fires) etc.","created_at":"2015-04-12T03:46:19Z","updated_at":"2015-04-12T03:46:19Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/CleverRaven/Cataclysm-DDA/pulls/11993/commits","review_comments_url":"https://api.github.com/repos/CleverRaven/Cataclysm-DDA/pulls/11993/comments","review_comment_url":"https://api.github.com/repos/CleverRaven/Cataclysm-DDA/pulls/comments{/number}","comments_url":"https://api.github.com/repos/CleverRaven/Cataclysm-DDA/issues/11993/comments","statuses_url":"https://api.github.com/repos/CleverRaven/Cataclysm-DDA/statuses/6e219f369b47ec0f0292d5ffcaed73f9c7c48109","head":{"label":"Coolthulhu:area-lambda","ref":"area-lambda","sha":"6e219f369b47ec0f0292d5ffcaed73f9c7c48109","user":{"login":"Coolthulhu","id":1878860,"avatar_url":"https://avatars.githubusercontent.com/u/1878860?v=3","gravatar_id":"","url":"https://api.github.com/users/Coolthulhu","html_url":"https://github.com/Coolthulhu","followers_url":"https://api.github.com/users/Coolthulhu/followers","following_url":"https://api.github.com/users/Coolthulhu/following{/other_user}","gists_url":"https://api.github.com/users/Coolthulhu/gists{/gist_id}","starred_url":"https://api.github.com/users/Coolthulhu/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Coolthulhu/subscriptions","organizations_url":"https://api.github.com/users/Coolthulhu/orgs","repos_url":"https://api.github.com/users/Coolthulhu/repos","events_url":"https://api.github.com/users/Coolthulhu/events{/privacy}","received_events_url":"https://api.github.com/users/Coolthulhu/received_events","type":"User","site_admin":false},"repo":{"id":23649904,"name":"Cataclysm-DDA","full_name":"Coolthulhu/Cataclysm-DDA","owner":{"login":"Coolthulhu","id":1878860,"avatar_url":"https://avatars.githubusercontent.com/u/1878860?v=3","gravatar_id":"","url":"https://api.github.com/users/Coolthulhu","html_url":"https://github.com/Coolthulhu","followers_url":"https://api.github.com/users/Coolthulhu/followers","following_url":"https://api.github.com/users/Coolthulhu/following{/other_user}","gists_url":"https://api.github.com/users/Coolthulhu/gists{/gist_id}","starred_url":"https://api.github.com/users/Coolthulhu/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Coolthulhu/subscriptions","organizations_url":"https://api.github.com/users/Coolthulhu/orgs","repos_url":"https://api.github.com/users/Coolthulhu/repos","events_url":"https://api.github.com/users/Coolthulhu/events{/privacy}","received_events_url":"https://api.github.com/users/Coolthulhu/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/Coolthulhu/Cataclysm-DDA","description":"Cataclysm - Dark Days Ahead.
