DefaultTimeline: make sure older tweets get removed

This did not work whenever the firt attempt to remove them failed.
HomeTimeline: Don't force_wait on scroll_top_next

This caused the user to be unable to scroll down whenever he received
mutliple tweets when not being at the HomeTimeline when they arrived.
Related to #49.
DMThreadEntry: Remove old debug output
DMThreadsPage: Correctly update the global unread count

We simply forgot to call update_unread_count on the page.
DMPage: Make user names clickable

... and show that user's profile page, like we do everywhere else.
HomeTimeline: Don't forget to scroll up if necessary

README: Update compose tweet shortcut(s)
AccountListEntry: Add some margin-top

With the new tabs in adwaits 3.12, the blue underline visually collides
with the blue used to indicate selected menu items. We simply add some
margin-top to every list item, which will keep it looking ok in adwaita
and won't hurt everywhere else.
HomeTimeline: Use foreach loops instead of GtkContainer's foreach
HomeTimeline: Don't show notification for mentions twice

See issue #53
TweetInfoPage: Fix scroll_event callback

... so scrolling down is possible again. m(
ui: Mark placeholders as untranslatable
HomeTimeline: Don't notify the user for 0 new tweets

This does not make sense for people who use auto-scroll-on-new-tweets
AND want to be notified after X new tweets. OTOH the unread_count
variable does not work like that at the moment.
ScrollWidget: Don't add more than 1 callback for scroll_up

This should hopefully finally solve the wrong scrolling.
TweetInfoPage: Handle Twitter errors more gracefully
Utils: Make show_error_object more robust

It now also works if the json stirng is malformed(in which case the
alternative will be shown).
Also, if the josn data does not contain an 'errors' array, but just an
'errors' string, we simply show that.
TweetUtils: Use show_error_object more often
Utils: Indicate that the error is an exception in show_error_object
