Fix: keep tank order stable on select

Tanks sharing the same tier, nation, class and type were shown in an arbitrary order that changed after selecting a tank. The meta sort had no tiebreaker, and the filtered list was sorted and reversed in place, so each re-sort started from the previous reversed order and flipped tied tanks around.

- Added tank ID as the first sort key in `metaSortTank` so tied tanks always come out in the same order
- Sorted a copy of the tank search results, pre-sorted by ID, instead of the cached list
- Added an `exclude` option to tank search and used it in Compare so tanks already being compared can't be added again, including through select all or by swapping another slot

Fixes #313
