[Gameplay A24] - Unify garrison heal rates.

Makes all (standard) structures don't heal at first, execept for the
wonder (heal rate of `5`) and temple (`3`).
Replaces the barracks healing technology by one that allows healing in
all structures (`+1`).

Summarising:
This patch makes the 0 rate the default and merges the technologies to a
single one, researchable at the temple, but affecting garrisoned units
in all structures, except for outposts and walls (i.e. those with
visible turret points). The new situation is:
```
0: structures by default
1: structures with technology
3: temple by default
4: temple with technology
5: wonder by default
6: wonder with technology
```
