Map: added show/hide ID toggle

[Dranni21312]

This adds a toggle to the map that shows or hides object IDs.

Once this branch successfully builds, you will be able to try the branch out for yourself by changing the "branch" in your updater to "map_hide_ids" (without the quotes).
This setting can be found under the "Updates" tab.

Don't forget to change back when you are done testing. You should reset your branch either to 'stable' for normal releases, or 'master' for beta builds.

Makes sense, I updated that.

One other minor improvement, if you move it up to line 686, then it will work immediately rather than waiting for an HP change (since the 'return' might make it leave that method early).

Done!
