Refactored dupeGuru to make hscommon.path's API a bit close to pathlib's
API. It's not 100% compatible yet, but it's much better than before.
This is more of a hscommon refactoring than a dupeguru one, but since
duepGuru is the main user of Path, it was the driver behind the
refactoring.
This refactoring also see the introduction of @pathify, which ensure
Path arguments. Previously, we were often unsure of whether the caller
of a function was passing a Path or a str. This problem is now solved
and this allows us to remove hscommon.io, an ill-conceived attempt to
solve that same ambiguity problem.
Fixes#235.
This unit hosts previously awkward UI view methods which weren't related
to the view itself, but to the current desktop environment. These
functions are now at their appropriate place.
Following the refactoring that has been initiated in pdfmasher's
"vala" branch, I pushed more progress window logic into the
core.
The UI code is now a bit dumber than it used to be, and the core
now directly decides when the progress window is shown and
hidden. The "job finished" notification is also directly sent by the
core. Job description update logic is handled by a core gui
textfield.
Job description contsants also moved to the core, triggering
a localisation migration from "ui" to "core".
