mobile, QML UI: margings and paddings in download screen

There was a significant of not needed whitespace on the download from
DC page. Most importantly, the bottom buttons where not on the bottom,
so we had to truncate the downloaded dives early (to prevent overflowing
the buttons). Further, a tiny bit of padding is removed between the
3 top pull down items.

All this, results in the diplay of more dives without scrolling.
For example, previously, only 1 dive (with 1 stored DC) was shown
on my 5.5" device, and now 3 (scale: regular).
