rules need namespace

[gitorgstars]

rules should be objects with properties such as rule.do_gen(), rule.num_states etc

bbRule.js:
bbRule = {}
bbRule.do_gen = function(grid, x, y, z, frm) {...}
bbRule.num_states = 2;
bbRule.color_odd_p1 = 0xff0000;
bbRule.color_odd_n1 = 0xffff00;
bbRule.color_even_p1 = 0x0000ff;
bbRule.color_even_n1 = 0x00ffff;

index.js:
rule = bbRule;
if (state==1 && phase % 2 == 1) color = rule.color_odd_p1;

note that functions such as add, vector, XOR as defined in rule2D3state are also defined in rule3D3state, in global namespace, so the last one included redefines these functions for both rules.
