[enhancement] Add missing bower.json.

#### Hey, maintainer(s) of LearnBoost/antiscroll!

We at [VersionEye](https://www.versioneye.com/signup?promo_code=BOWER) are working hard to keep up the quality of the bower's registry.

We just finished our initial analysis of the quality of the Bower.io registry:

**7530** - registered packages, _224_ of them doesnt exists anymore;

We analysed **7306** existing packages and **1070** of them don't have bower.json on the master branch ( _that's where a Bower client pulls a data_ ).

Sadly, your library `LearnBoost/antiscroll` is one of them.

Can you spare **15** minutes to help us to make Bower better?

Just add a new file `bower.json` and change attributes.

```
{
"name": "LearnBoost/antiscroll",
"version": "1.0.0",
"main": "path/to/main.css",
"description": "please add it",
"license": "Eclipse",
"ignore": [
".jshintrc",
"**/*.txt"
],
"dependencies": {
"": "",
"": "",
"": ""
},
"devDependencies": {
"": ""
}
}

```

Read more about bower.json [on the official spefication](http://bower.io/#defining-a-package) and nodejs [semver](https://github.com/isaacs/node-semver#ranges) library has great examples of proper versioning.

**NB!** Please _validate_ your bower.json with _jsonlint_ before commiting your updates.

Thank you!

Create the requested bower.json at the repository root, using the repository contents and the official Bower specification to replace the example placeholders with project values. Validate the completed manifest with jsonlint; done means a valid bower.json is present on the master branch.
