Fixed undesired line breaks and Markdown syntax for Links.

Hello!

I fixed some minor bugs that were preventing me to be able to use geeknote properly, hope you find then useful as well.

Cheers

More information here (from the commit message):

The mentioned line breaks where corrupting URLs, after some default line length, so text was being split into lines automatically (and therefore corrupting URLs).
Links of type http://someurl.com can be expressed as http://someurl.com, so we have to tell the markdown processor to handle it like such.

@AntonioInacio, thanks for the fixes. You'll see that the tests are now failing, though. Would you correct the errors, and also maybe insert a new test that exercises your changes?

Upps sorry about that!
Will look into it and give you feedback.

Cheers
