Add debug-info command line option.

In reference to #71
Allow user to get basic debug info, so they can paste it into a GitHub
issue. Ruby(Version, engine, platform) MetricFu(Version, dependencies)

Thanks for this. Some suggestions:

Use only methods on MetricFu::Environment (include Environment)

If the method you need isn't there, add it. e.g. ruby_version ruby_platform ruby_engine. See redcard

RedCard.engine => 'ruby'
RedCard.engine_version => '1.9.3'
RbConfig::CONFIG['host_os'] => ''darwin'
RbConfig::CONFIG['host_cpu'] => 'x86_64'
RedCard::CONFIG['build'] => 'java1.6'
RbConfig::CONFIG['build'] => "x86_64-darwin12.4.0" 
RbConfig::CONFIG['prefix'] => "/Users/bfleischer/.rvm/rubies/jruby-1.7.4"
RbConfig::CONFIG['prefix'] => "/Users/bfleischer/.rvm/rubies/ruby-1.9.3-p448"
$VERBOSE => [false, nil, true]
Gem::VERSION
# to consider
Encoding.default_external.to_s => 'UTF-8'
Encoding.default_internal.to_s => ''
RUBY_DESCRIPTION => '=> "jruby 1.7.4 (1.9.3p392) 2013-05-16 2390d3b on Java HotSpot(TM) 64-Bit Server VM 1.6.0_51-b11-456-11M4508 [darwin-x86_64]"
RUBY_PATCHLEVEL => '392'
RUBY_VERSION => '1.9.3'
$LOADED_FEATURES
$LOAD_PATH

MetricFu version is fine, of course, as is.

I'm curious why you're collecting the immediate dependencies. That's what's effectively specified by the gemspec.

You don't need to use all those variables, they're just what I thought of while commenting. I'm interested in what you think would be useful, as well.

[bf4]

Awesome, thanks! I added some comments

[bf4]

Thanks for your PR's! Very much appreciated!

Do you need help finishing this? There's been a lot of changes to master you'll have to rebase off of.

[calveto]

I haven't had a chance to look this over too much, so I don't have any question at this time. I don't mind rebasing. I hope to have a look at it this weekend.

[bf4]

Want to pair on this to finish it up?

[bf4]

Hey @calveto can I help?
