Fix: Show sdoc version rather than rdoc version

[strzibny]

sdoc --version should return the version of sdoc and not version of rdoc.

[zzak]

I'd like to get this merged, but it's an unrelated feature, so it will have to wait until we can bump rdoc and do a release.

Thank you!

[zzak]

Also, I think we should do something like if ARGV.include?("--version")

[zzak]

Could you rebase this? Thanks!

[strzibny]

@zzak I will.

[strzibny]

Edited and rebased. You can cherry-pick if you wish.

[zzak]

I will accept a patch for lib/sdoc.rb and sdoc.gemspec, but I cannot accept the bin patch without a test (and even then I think we will wait until the next patch level version).

If you could send me a patch for just that I will gladly merge it before doing the release of 0.4.0.

Thanks!

[zzak]

Sorry to be so picky, I have limited time for SDoc at the moment.

[zzak]

@strzibny Thanks I've applied parts of your commit to lib/sdoc.rb and cherry-picked the sdoc.gemspec change.

Please send a separate patch for the --version option and we can discuss it after the 0.4.0 release
