Simpler usage of Almond

[kirill-konshin]

You can simplify the documentation by adding the following:

var addSrc = require('gulp-add-src');
//...
            .pipe(amdOptimize('app', {...}))
            .pipe(addSrc.prepend(require.resolve('almond')))
            .pipe(addSrc.append('_start.js'))

where _start.js content is one-liner:

require('app'); // should match amdOptimize's first parameter
