First version of the metatracing VMs benchmark.
Second version of the metatracing VMs experiment.

This adds in many benchmarks from the Computer Language Benchmarks Game and
support for many more VMs.
Add C benchmarks and remove as many threaded benchmarks as possible.
Ignore temporary LaTeX files.
Add ability to produce HTML output of results.

Ultimately, it might be useful to include the outputs of running this on
multiple machines, so we also include the dmesg.
Add the date & time the results file was last modified on.

This should save confusion over which file led to the creation of which HTML
file.
Clarify sentence.
Automatically create results.html.

It's a lot easier than making comparisons from the raw multitime output!
Use a less mystifying name for the results formatter.
Check for unzip before attempting to build.
add Topaz ruby impl
parameterize run_benchmarks script
untabify
Merge branch 'master' of https://github.com/timfel/metatracing_vms_experiment into timfel-master

Remove a few stray "-q"s left over from Tim's changes.

Should be no functional change.
Reformat to 76 characters.
Update the VMs to the latest available versions.
Topasz doesn't yet work on enough benchmarks to be enabled by default.
Add Javascript and V8 to the benchmarking suite.
