Take care of all personal links (dropbox, google drive, etc)

[vhf]

Let's start with:

Here is what I suggest:

1. As always, check if it's free.
2. Then find alternative link, ideally original source or author's website
3. If no good alternative link can be found, remove it anyway.

I may add a rule to the linter for this issue. If someone wants to help, you can provide regular expressions for dropbox URLs, google drive URLs, etc.
