Rework grunt tasks

[acrobat]

This pull-request will rework the grunt tasks and prepare the repository for the new release process.

Todo's:

• Update dependencies to higher version
• Rework current grunt tasks
• Create tasks for new release process to dist folder and dist.zip
• Clean javascript/css against the jshint, jscs, css lint rules
• Add version to banner of dist files

Fixes: #1166

After this PR is merged I will create a new pull request to introduce some new/stricter js rules and include the css lint rules in the grunt test task

This would be cleaner using Array#join:

    banner: [
        '/*!',
        ' * Datepicker for Bootstrap v<%= pkg.version %> (<%= pkg.homepage %>)',
        ' *',
        ' * Copyright 2012 Stefan Petre',
        ' * Improvements by Andrew Rowls',
        ' * Licensed under the Apache License v2.0 (<http://www.apache.org/licenses/LICENSE-2.0>)',
        ' */'
    ].join('\n'),

Also, either you're missing a "<" in the license link, or you have an extra ">" at the end of it.

Fixed and removed the < & > around the url!

This PR is ready now, can you guys do a quick review. The grunt tasks have changed a bit so that we always have a dist folder with the files of the latest release, the version is now included in the files banner and the js/css rules are now correctly applied.

Currently I didn't change any jscs rules and disabled the css lint task as I'm going to create a new pr to discuss new/stricter rules and clean up the css lint issues.

The plan is to have this PR merged this week, after that I fix PR #1205 and close all related issues.

@acrobat lgtm, but i would add version info, licence in a short form also in css and min.css

[acrobat]

Hmm that's something that supposed to happen, I will fix that tomorrow!

[acrobat]

@hebbet I've pushed a new version of the grunt tasks the issue with the banner in css files is resolved.
