Links not picked up correct

Hello!

First, big thanks for a great plugin. It is working very well! But I have a few smaller problems I don't know how to fix.

This link gets totally messed up by the script:
https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Hermann_Hesse_2.jpg/200px-Hermann_Hesse_2.jpg - Output:

```
https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Hermann_Hesse_2.jpg/200px-Hermann_Hesse_2.jpg.' target='_blank'>https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Hermann_Hesse_2.jpg/200px-Hermann_Hesse_2.jpg.
```

info@wikipedia.org - Output (Missing "mailto:):

```
info@wikipedia.org
```

Also this one does not get picked up by the script:

```
http://www.wikipedia.org.
```

If you want to try it out yourself run...

```
jQuery(".linky-test .journal-content-article").linky();
```

... through the console on http://arenagodemo.axiell.com/web/arena/welcome and see the result in the text at the bottom, above the footer.

This is the markup I am running the script on (A lot of bullshit text in Swedish, but it is the links in here I want to render correctly):

```

Denna ska inte tas upp wikipedia.org. Men denna ska tas upp www.wikipedia.org, lika så www.axiell.com. Även denna ska tas upp, http://www.wikipedia.org och http://www.axiell.com. Denna bör ju också tas upp; http://wikipedia.org.

Detta är en URL till en bild och borde också göras om till en länk, https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Hermann_Hesse_2.jpg/200px-Hermann_Hesse_2.jpg.

Emailadresser fångas också upp, men behövs egentligen inte: info@wikipedia.org.

Här är en färdig html-länk och den ska inte tas upp, http://www.wikipedia.org.

En HTML-bild:

Grateful for help!

Joakim
