- Resolves: #334

Let's close properly without segfaults :)

- Resolves: #243

just a minimal boilerplate. the idea is to import the qml files and
assert that the states/widgets change accordingly if we mock the backend
status.

- Closes: #300

- simplify notification routine (we dont need no rejected action). we
  just check every hour, as in the original code.
- open links directly from Qt
- rename some global variables to make them less cryptic
- move cleanup function to the same module that created them

first pass on giving functionality to the donation reminder

for some reason I don't understand, explicit activations end up in a
segfault when I try to call menu.open() from the signal handler. i'm ok
not handling middle clicks if that means I can stop digging in search of
the real reasons, to be honest.

- Fixes: #299
