New landing page

In our new landing page at https://orgpad.com/l/intro, we try to showcase how OrgPad works and that it offers a beautiful design and great UX. We spend a lot of time thinking how to design the landing page, and we decided to cover most of the landing page with mock-ups of OrgPad itself. The goal is to introduce OrgPad quickly and grasp user's attention by a different presentation of the tool.
