This commit is mostly "if Windows, skip these tests" but unfortunately Windows is not POSIX compatible so certain things don't even work on Windows (chmod for instance). I'll try to make symlinking work properly first and then see if I can get chmod working.

Tests for test -L is also tricky because git on Windows checks symlinks as normal files with symlinked filename as the content making it impossible to use the links in resources directory on Windows. Once/if ln -s is fixed, we may use that to create links and then test them.

@BYK looks like there's some merge conflicts. Could you resolve?

@ariporad Do you think we should merge, or wait until chmod and ln have their Windows-incompatibility documented? This blocks #299, which is a priority.

I'd advocate for merging #299 first to ensure these fixed tests work in AppVeyor before merging.

@nfischer done

@BYK could you rebase off master one more time? That will make sure AppVeyor runs checks on the code

@nfischer done :)

@BYK could you modify test/shjs.js? I think we need to change:

  return shell.exec(path.resolve(__dirname, '../bin/shjs') +
                    ' ' +
                    path.resolve(__dirname, 'resources', 'shjs', name), { silent: true });

into:

  return shell.exec((process.platform === 'win32' ? 'node ' : '') + // call by path for unix, call with 'node' for Windows
                    path.resolve(__dirname, '../bin/shjs') +
                    ' ' +
                    path.resolve(__dirname, 'resources', 'shjs', name), { silent: true });

I think the issue is that Windows can't call the .js file directly, while we expect OSX/Linux to be able to.

@BYK Also, awesome job fixing the other tests! It's great to finally have (almost) all the tests passing on Windows.

@BYK or you can just rebase off of the branch in #315 (or off master if it gets merged). This contains the fix I wrote above for the shjs test.

I'm going to go ahead and merge this, since I tested it in a separate branch, and I tested it rebased off master and it passes appveyor CI now that #315 is merged 👍

@BYK Thanks again for all your help! This rocks!

@nfischer - glad I could help. I'm planning to help with other Windows issues too. Just don't have a much time. May be over the weekend :)
