Add versioning for react-bootstrap and bootswatch

[108krohan]

Added versions for react-bootstrap and bootswatch. Proofs:

• React-bootstrap on latest version:
  • Navbar.Header issue stackoverflow - react-js-navbar-header-element-type-is-invalid
  • Grid re-name Grid component rename in later version to Container via this.

Btw, thank you for the clear explanations. Thanks to you I am able to create my very first (even if real bare bones) React app! The app: http://toomuchof.me :D
