Mining computation update

Browse source 
* Added various views and helper functions used by the mining
computation but which may be re-used in other parts.

* Added mining computation update type and associated update function

* New constants: game.resources.weightBase (the value used to compute
weights from mining settings) and game.resources.extraction (the
quantity extracted in a day from a full provider at difficulty 0)
