[addon] Temple

[Krugslayer]

Building requirements:
- Temple should require as much building materials as Fortress
- should be classified as a 'big' building
- only one temple can be build

How it should work:
- to 'activate' Temple, you should sacrifice 9 pigs or/and also 9 beers or/and something new (new production line, undecided yet)
- Temple can be activated for 10 minutes (for example)
- Temple should boost your soldiers:

a)
When 'activated' it could increase the number of 'hit points' of all of your soldiers. For example private must be hit 3 times to die and general must be hit 7 times to die. With temple 'activated' private will have to be hit 4 times to die and general 8 times to die

OR

b)
When 'activated' it could increase (by few %) the chance of each of your soldiers to hit enemy soldiers or decrease (by few %) the chance of enemy soldiers to hit your soldiers (doesn't matter if private or if general).

 OR

c)
When 'activated' you are able to create 2x more soldiers than normally:

- you need only sword + beer or only shield + beer to create soldier

OR

- you need sword + shield + beer to create 2 soldiers instead of 1

How to enable this addon:
- this addon should be optional. Should be available like other RttR addons (in options).

Why this addon:
Religion is something that should be implemented in this game for historical reasons. Religion was present in many cultures from the beginning. Besides I wanted to:
- find an alternative way to boost soldiers
- find a second purpose for pig farms
- find a second purpose for brewery
- create a new production line
