Add Calq

[rinopo]

"Calq is an easy to use, on demand calculator."

I followed git-annex.rb to force the .dmg file extension to the gzipped container. (cf. #3650)

@vitorgalvao This Cask is technically okay, but it uses a "horrible hack" so it's questionable if we should merge it (even though we do already have a cask with the same behavior, git-annex)

[vitorgalvao]

Yes, it’s OK to merge, I’d say.

This will cause problems on case-sensitive filesystems. Needs to be Calq-#{version}

Hi,

Thanks @jawshooah for pointing out. I've made the fix.

@adityadalal924
Thank you for your consideration.
I'd argue that this cask shouldn't do any harm at least on the end user's side.
fuse.rb which uses (to my eyes) essentially the same technique has been merged 3 days ago, and there seem to be a few more examples.
And I find calq.app itself is, old it is, still quite useful ;)

@rinopo To clarify, @adityadalal924 wasn’t exactly worried about any harm caused by the cask, but rather that we frown upon these types of hacks (we prefer to fix the core issue).

Could you please squash your commits?

[rinopo]

@vitorgalvao Thanks. Squashed.
