DevelopingTom 3b9e94ddb9 Improve border drawing performances (#751)
## Description:
When drawing the border colors, the territory layer is using the generic
`nearbyUnit` function to check if any allied outpost is nearby.
But `nearbyUnit` is uselesly computing the distance with all units,
which is very costly specially in late games with plenty of units.

Early game (<1 min):

Late game (> 10 min):

This PR adds another function tailored for this requirement.
## Improvements:
- New `hasNearbyUnit()` function stopping at the first correct unit,
rather than computing the distance with every unit
- Check the unit type before computing its distance
- Selecting the correct cells:
The previous algorithm was very generous and looking at cells uselessly.
Admittedly this is marginal but since it is called on every border pixel
change, we should squeeze the most performances out of it.
