update to bootstrap v4.1

[m5o]

Hey @stefanneculai 👋

Bootstrap released their final v4.0.0 back in January. 💜
Would like to contribute some work I've started with 4.0 and now 4.1.
Hope you're interested in this update and some more cleanup around that.

@m5o do you think you could make a PR?

@stefanneculai It's seems bootstrap is shipping 4.1 in the next hours/days. Will wait for this release, to adopt all features to design-blocks and will open my PR then.

🗽Just my 2-cents on the custom License you choose. I really liked the idea of the bootstrap design components you build, it's definitely nice and a jump start for a lot of people using the framework. If you look around, creative spin-offs where created this way. The Bootstrap ecosystem is amazing! 💜

🎨 Bootswatch for example with 20+ free themes or 🗜 Bootstrap.build to customize or create a new theme. They even build a theme import which is amazing proof of well documented free resources ✨

There are already some discussions about license recently, because every custom license is hard to understand. A minority of users is asking questions here and open Issues, but a majority isn't and just step away because the license situation is unclear. Think about that.

Totally understand why you choose this license, to avoid that people use it to create templates, themes, and plugins for sale. To be honest, design-blocks is just build on top of bootstrap. It's a pre-composition of standard bootstrap markup components. Bootstrap ship's with a MIT License.
So if someone has some spare time, he/she could create a copy...ähm "is inspired by"-version of design-blocks or Startup Components based on bootstrap without mentioning this project by a single word.

🏁 Use the momentum around bootstrap to build great tools and help people build great and accessible websites. Use the momentum of people trending this repository. Your company and employees will benefit from the community contributions and feedback. Choose a open license model that supports this why-type idea you had with this repository. 🙏
And if froala design-blocks get integrated by some other spin-off, it's just great news and you'll be promoted by another amazing open-source project. 👑

🖖 🤓
