Materialize app list
Improve the look of app list items. Note that compact mode is removed because it does not make much sense, see the screenshots.
Before (default layout, compact layout):


After:


Affects #471 and #467. Those bugs will still be relevant because there are other places with wrong padding and font style.

If getSystemService(Context.DOWNLOAD_SERVICE) returns null, we should not go
ahead with using AsyncDownloaderFromAndroid. This would result in NPE and
crashes.
Fixes#442.
As the comment says, this should not be on until it can be opted out from. The
biggest problem is unwanted repo updates, e.g. when a user is on a mobile
connection.
Fixes#435.
The idea was good, but it applied the second-precise date format everywhere.
This broke dates on apps and apks, which have the format yyyy-MM-dd on the
index.
Fix this by having two sets of funcs in Utils, one for dates (precise to a
day) and one for times (precise to a second). We should use the latter for
dates we ourselves measure, like the last repo update time.
Add night theme

The screenshot is huge, so making it an image in markdown takes up a lot of space. Hence link.

Similar to the dark theme, but dropping blue in favour of very dark shades of
grey.
Removed colorEdgeEffect to simplify the sharing of the style between dark and
night themes. It should default to colorPrimary anyway, so we're good.
Fixes#345.
This change primarily affects the AppDetails links section to make them easier to click. It also strips down the UI a bit to provide a cleaner interface as well as some modest Material Design tweaks.
Fixes#389.
