When trying the _TweetRemainingCharacters_ for a Tweet with a link to Google, I'm getting the wrong number of characters returned. It seems the link isn't detected correctly.
```
var twt = Tweet.CreateTweet("The quick brown fox jumps over the lazy dog. My dog is freaking amazing. https://www.google.nl/search?q=dog&source=lnms&tbm=isch&sa=X&ei=IZ7fU-CwJIO50QWtmICoCA&ved=0CAgQ_AUoAQ&biw=1528&bih=876");
int remaining = twt.TweetRemainingCharacters();
```
The answer is __-45__, but I expect (+) __44__.
