Updates to datacrow package

[digital-carver]

Attempts to update the datacrow package related files, to get it working again (which would, for eg., resolve #349).

I'm new to ketarin and chocolatey package internals, so I kinda bumbled through the changes especially since I don't have things set up for testing. If there are any mistakes among the changes, I hope this can still serve as a jumping-off point for updating the package.

Of course, right after making this PR I realize the filehippo download URL used in the last commit is not a download URL at all. (Local confusion with the 'Filehippo ID' option lead me to thinking it was.)

I'll see if that part of the PR can still be salvageable by perhaps using some other host (or are there other ways to get filehippo sourcing work?), within the next few days.
