If you're like me and you use semver for versioning your tags, you probably hate when you do this:

$ git tag -l
0.1.0
0.10.0
0.2.0
0.3.0
0.3.1
0.4.0

0.5.0

function dataURLtoBlob(dataurl) {
    var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
        bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
    while(n--){
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new Blob([u8arr], {type:mime});
