Change landing page title

[lmuntaner]

Motivation

Change the copy of the landinga page as requested.

Changes

• Change the copy of the landing page title.
• Split the copy in two to make sure it's always shown separately. It was ugly with any other split.
• The second line was sometimes overflowing a big just before the breakpoint and turning into two lines (three in total). This was ugly and instead of changing the padding to adapt to it, I used word-wrap to ensure the line is kept whole even when overflowing. It only overflows a bit, so it's not noticeable.
