Fix levels of progress -- or rather change the way we get experience

Seems like the levels of Smithing/Mining are messed up.

Lines 241 to 251 in 8e6755f

    
           static getLevel(exp) { 
        
             let level = 1; 
        
             let calcExp = 0; 
        
             while (exp > calcExp) { 
        
               calcExp = UI.getExperience(level); 
        
               if (calcExp > exp) break; 
        
               level += 1; 
        
             } 
        
             return (level - 1); 
        
           }

Specifically, that there is what is causing players to level up. Perhaps, since it's only levels 1-99, we don't really need to get the experience via formula but rather just a key/value pair.

Level 2 shouldn't start until, at least, ~80 experience points. We're following the same trajectory of RuneScape but a tad smaller. So Level 99 is around 10 million exp.

	static getLevel(exp) {
	let level = 1;
	let calcExp = 0;
	while (exp > calcExp) {
	calcExp = UI.getExperience(level);
	if (calcExp > exp) break;
	level += 1;
	}

	return (level - 1);
	}
