Disable a few travis builds to speed us up

[scravy]

Disables two travis builds and runs them in the daily cron job (at night) only.

• The windows 64 bit one (win32 bit should be sufficiently similar to the win64 bit build and sufficiently different form our 64-bit linux/unix machines).
• One of the builds which run functional tests. There's still a 32-bit and a 64-bit build running functional tests on linux.

Here's the documentation on conditional builds in travis:

• https://docs.travis-ci.com/user/conditional-builds-stages-jobs/

And here's the documentation on the available conditions:

• https://docs.travis-ci.com/user/conditions-v1

This is to tackle our long travis queue.

I like the idea. Concept ACK.

@cornelius I implemented the only-run-in-cron-job feature too, which also makes it just a two line change.

utACK 19fb12e , nice to save some build time.

Yeah, I saw that. That's really nice.
