Asobu 0.1.2

Make the installer splash the launcher's own opening

The splash led with the logo and its own wording, so installing Asobu and first
running it read as two screens that happened to share a colour. It is now the
same two lines the launcher opens with -- "Welcome to" over the name -- in the
same sizes, the same weights and the same pink.

The launcher animates those lines in; this holds them. Velopack shows the image
for as long as the install takes and loops it, so a fade-in would restart over
and over in front of whoever is watching. What moves instead is a glow behind
the name, breathing on a sine across the frame count so the loop has no seam.
