getExperience and getLevel should return -1 if not logged in

Currently they return 0, which is BAD.

 

Nah, this is expensive:

Code (Text):

1. public class RMSkills implements Skills.Tracker.Provider {
2.  
3.     @Override
4.     public int getCurrentLevel(com.skelware.bot.data.Skill skill) {
5.         if (!RuneScape.isLoggedIn()) {
6.             return -1;
7.         }
8.  
9.         return convert(skill).getCurrentLevel();
10.     }
11.  
12.     @Override
13.     public int getCurrentExperience(com.skelware.bot.data.Skill skill) {
14.         if (!RuneScape.isLoggedIn()) {
15.             return -1;
16.         }
17.  
18.         return convert(skill).getExperience();
19.     }
20.  
21.     private Skill convert(com.skelware.bot.data.Skill skill) {
22.         return Skill.values()[skill.getGameIndex()];
23.     }
24. }
