Build fails on version 0.4.46

Hi @flauc

Importing angular2-notifications on an angular2 project causes the following error on compiling time: error TS6059: File 'c:/.../node_modules/angular2-notifications/src/icons.ts' is not under 'rootDir' 'c:\...\app\'. 'rootDir' is expected to contain all source files. ...

This error could be raised because .ts files are included on the npm package. Downgrading to 0.4.41 fixes the problem.

Thanks for the library btw!

My temporary solution, I removed the .ts files 🙈

const del = require('del');
gulp.task('prod:clean', function () {
    return del([
        'node_modules/angular2-notifications/**/*.ts',
        '!node_modules/angular2-notifications/**/*.d.ts',
        'dist/*',
    ], {force: true});
});

@jhonmike probably not the best solution but useful until the bug is fixed. Thanks!
