iojs support

[mnutt]

This allows node-sass to build on iojs. Tests suite passes with iojs 1.0.1 and node.js 0.10.31. Are there other node versions that should be tested as well?

Addresses #627.

One thing to note when manually rebuilding is that upstream node-gyp doesn't yet support iojs, so you need to make sure you're building using node-gyp bundled with iojs: nodejs/node#433

Coverage remained the same when pulling 0887f83 on mnutt:iojs-1.0.1 into 604ccf5 on sass:master.

HI @mnutt, thanks for the contribution.

Can we test the build against io.js on Travis-CI?

[mnutt]

@am11 unfortunately travis-ci doesn't yet have support for iojs, it looks like they're waiting for nvm to support it: travis-ci/travis-ci#3108

[am11]

@mnutt, brilliant. TravisCI can wait then. :)

@browniefed, if you can redo the Mac binary with these changes, I will merge this in for v2.0 (Edit: would require to delete node_module dir, npm install and then node-gyp rebuild). :)

@mnutt, on a separate note, can you please provide some pointers (or preferably an example of binding.gyp) on how to statically compile libstdc++ on Linux targets? LiibSass is using C++11 features and we are obliged to use gcc v4.6 (and GLIBCXX 3.49), while our target audience is mostly using CentOS 5.5+ (with GLIBCXX 2.14). That is a major show stopper for us ATM.

Related discussion #602 and #517.

@am11 will get to this some time this weekend.

@browniefed, excellent! So this should be merged then. :)

Thanks again @mnutt! 🎉
