Create a disableLuck url param flag

[W01fw00d]

Refactor a Random module and set a flag to “disableLuck”, meaning that the output of Random will be strictly predictable.

Random will include:

• Random decision for AI movements and similar (will always pick the first available option)
• Random resolution of combats with similar strength units (will always favor the human)

This flag will allow to strictly test combat an AI turn (at least meanwhile AI turn decisions are completely random instead of based on algorithms).

Also, it will be useful for manual debugging.
