Title: pass opts to gulp tag to be able change cwd for example

Hey!
Thanks for your useful plugin!
Could you please approve this pull request?
I want to support version bumping in bower(bower rely on tagging). In [my project](https://github.com/lapanoid/gulp-webpack-seed) I manage distrs as gitsubmodule, so I need to pass cwd like that:

```js
gulp.task('ololo', function(){
return gulp.src('./bower.json', { cwd: './dist' })
.pipe(bump({type: 'patch'}))
.pipe(gulp.dest('./',{ cwd: './dist' }))
.pipe(git.commit('bumps package version',{cwd: './dist'}))
.pipe(filter('bower.json'))
.pipe(tag_version({cwd: './dist'}));
});
```
