Practically all fauna have a 2:1 length to width footprint ratio. However, citizen cavalry has a 3:2 ratio and worker elephants a circular footprint. This patch changes their footprints to the more appropiate 2:1 ratio.
Before: {F1476733}
After: {F1476746}
Also tweaked footprint height to:
* dog: 1.5
* infantry: 4
* cavalry: 6
* kush and ptol camel: 7.5
* maur elephant archer: 9
* maur worker elephant: 8
[EDIT]: Further changes:
* Standardized <StatusBars/HeightOffset> to <Footprint/Height> + 1.
* Removed some unnecessary footprint lines from infantry templates.
* Made use of D2844/rP23900 by @Angen to give heroes the same footprints as their citizen counterparts.
A larger footprint also makes units more vulnerable to long range projectiles (e.g. arrows), so this patch makes citizen cavalry a smaller target. For comparison:
```
infantry (b/c/h) footprint: 7 (circular)
cavalry footprint:
citizen: 24 → 18
champion: 20 → 18
hero: 20 → 18
elephant footprint:
worker: 50 → 40.5
archer: 38 → 40.5
champion: 38 → 40.5
hero : 28 → 40.5
```
i.e. about a 2 : 5 : 12 infantry : cavalry : elephant ratio.
