Title: update skim to v1.4.5

Hi there.

I updated cask of skim, a pdf viewer, to reflect its version 1.4.5 .

Download url, version and sha1sum are updated.
The updated cask has been tested locally with `brew cask install` and `brew cask audit`.

I'm new to brew and cask. So please let me know if I did something wrong.
