Move to 0.5-defensive Travis settings

[IainNZ]

I saw @tkelman do this

[tkelman]

Though I think Example.jl isn't on the docker workers so that job of mine is still queued. You'll only be getting RC's with 0.4, you could leave nightly in unless you think Julia master is going to start going nuts soon.

[tkelman]

Failure is due to COIN-OR not being back up yet. RC1 looks like it works though.

[IainNZ]

Yeah I suppose we can take out 0.5 if it does go nuts, might as well keep in for now. We'll be dropping 0.3 support soon enough anyway.

You'll only be getting RC's with 0.4

And 0.4.0 right, eventually?

[tkelman]

You're deleting nightly here currently. And yes, once 0.4.0, 0.4.1, etc are ready then 0.4 will use whatever's newest.

[IainNZ]

But there isn't such a thing as 0.4-nightly anymore right, nightly=0.5?

[tkelman]

correct, that's what I meant by "you'll only be getting RC's"

[mlubin]

All passing now

[IainNZ]

Nice. So @mlubin, do you think 0.3/0.4, or 0.3/0.4/nightly?

[mlubin]

I don't see the harm in running with nightly.

[IainNZ]

Indeed. I guess its weird right now, does release point to 0.3 and nightly point to 0.5, with no one running Travis against the RC? I guess RC and 0.5 are approximately equal, but still, kind of amusing.
