Crawljax is aware of second URL, but unable to open it.

This is still not working version. I commit this since I want to change
some code and I might use the code in this version in the future.
Issue is implemented. Read below:

Crawljax now has a function called alsoCrawl(String url)
with this function, crawljax will be able to crawl 2 or more different
URL at one time.
It has a minor bug though, it tries to open the last URL you specified
twice, but other than that it works totally fine.
Will need to work on that issue.
