This patch introduces three cheap technologies, one for each phase, that each give centres (including colonies and crannogs):
* +1 default arrow count;
* +5 capture points regeneration rate (i.e. countering the attack strength of one enemy champion);
* +10 vision range (allows seeing long-range artillery).
To compensate, centres start with 0 arrows and default <Capturable/RegenRate> (0.5), instead of 3 and 5. This makes capturing centres easier, especially in the village phase, but a bit harder when all three technologies are researched.
The idea is this patch can work both with or without D2845.
