Less transparency for the logo

There were some complaints that the logo is too transparent, making it
hard to see on gray backgrounds and in the recent tasks list.

So let's fill the transparent parts. No visible change for dark
backgrounds, slightly less elegant (but still ok) for white background and
much better for gray background.

Remove downloaded file in case of errors (e.g. wrong checksum)
Fix download info text being cut off

Not sure why, but this seems to fix #181.
Add known issue for Huawei and Nubia ROMs
Use dark background for application startup

This does NOT change the default theme. However, it's probably more
acceptable to switch from dark to light background than the other way
round, because it's not "blinding" the user.

The alternative would be a transparent background (only the action bar
showing up), but it doesn't look better in my eyes.

Fixes #180
Use darker cards for black theme
