Recognize 'blob:' URLs as absolute

[zlamma]

With blob URLs you can play with single-page-components purely in the browser.
E.g. you can feed Ractive.load a URL constructed from a string like this:

var template = '<script>component.exports ={ data:{ Name: "Alice" }}</script>'+
              '<h3>Hello {{Name}}!</h3>';
var url = URL.createObjectURL(new Blob([template], { type: 'text/html' }))
Ractive.load( url )
    .then(ShowItSomewhere)

Or, better yet, from a text input box on a component editor page.

Probably requires tests 😄

Would love to but it's the harder part for me. Currently fighting with getting the thing to build and pass tests on Windoze, as this is what I'm currently stuck with 😩. Plently of tests failing because of line endings :(

UPDATE: OK. I think I nailed the Windows problem and I think it can be fixed in the repo for everyone using Windows. Please see pull request #29 . If you merge it, it will make it easier for me to update this PR with a test :)

Added the test now & forced.

Alternatively, not to bake in too much complexity into this dumb logic, rcu can be made to work with URL objects (browsers, node), which are always absolute.
But how would we detect them cross-platform way? Perhaps checking existence of a property that exists in both node and browsers, like href?
