Don't add "*" prefix to the browser name

[anton-107]

My environment contains browser names, that don't start with * like "Firefox on Windows", so i had to comment out this.browser = '*' + this.browser; so that soda.js could connect to them

hmm, i'm not sure if they are mandatory. I would just rather the user not have to prefix them. Maybe some sort of compromise, I'd like to try and hide the ugliness of selenium
