Update VMs and SqueakSSL plugin

[fniephaus]

Hi Dale,
@krono and @marceltaeumel fixed the SqueakSSL plugin:
http://forum.world.st/SqueakSSL-Binaries-td4820846.html

This PR replaces the binaries accordingly and removes unnecessary libssl dependencies.

Cheers,
Fabio

@fniephaus an error occurs during Pharo4.0 install:

RUNNING TESTS...
ioLoadModule(/home/travis/build/dalehenrich/builderCI/images/pharo-vm/libSqueakSSL.so):
  libssl.so.1.0.0: cannot open shared object file: No such file or directory
==== Startup Error: ZdcPluginMissing: SSL/TLS plugin initailization failed (VM plugin missing ? OS libraries missing ?)

Is it unrelated to your changes or not ... BTW travis-ci was non-oprational most of the day ...

[dalehenrich]

On second thought this may be unrelated but may point out that the os dependencies of Pharo4.0 have changed out from under us ...

[dalehenrich]

If Pharo4.0 is the only failure, could you update the .travis.yml with Pharo4.0 as an allowed failure? I'll have to fix Issue #94, sooner rather than later ...

[fniephaus]

@dalehenrich I've re-added libssl1.0.0:i386 for Pharo and it's working just fine.
Also, I used the opportunity to update the vms.
There was still something wrong with the new SqueakSSL plugin, but I believe @krono has fixed it.

Once this PR is merged, we should publish a new builderCI release...

FYI: https://github.com/itsmeront/squeakssl/releases/tag/v0.2.0

[krono]

hold on … oh well…

[fniephaus]

For some weird reason the GemStone-2.4.5.3 job [1] failed and I couldn't restart it. Apart from that, everything should work just fine. If it doesn't, I have to revert the changes...

@krono btw: libssl0.9.8:i386 is not available anymore anyways:

[krono]

please re-grab the SqueakSSL…

[fniephaus]

btw: all builds passed

[krono]

Thanks again.
