Revamp of the landing page

After fixing outstanding issues, I've decided that it's time to consider v.1.0 done and start promoting it.

As part of this push to promote it, I revamped the landing page:

• I found out that most people didn't even try, to make their lives easier, I added a GIF on the landing page, to show-case what's possible
• I slightly improved things here and there to give the landing page a more modern look

Next step:

Promoting "https://formulairemagique.fr/open/PDF_URL_HERE" to open PDFs as I see no use of it at all (it's hidden in the tutorial) yet every single person I've talked to was really interested in the feature.

That would be a shame it it remained unknown when it's already built and working beautifully

Until next time!
