To avoid all sorts of problems, we need to ensure cards scheduled with
the V2 scheduler are not studied in older clients. Unfortunately we
can't just bump the file's schema version, as the existing clients will
freely import files created with newer versions. This patch changes
that, so things should be a bit easier in the future.
In the mean time, we need a way to prevent older clients from importing
files created with the V2 scheduler. To do this, we switch to using a
'collection.anki21' file in the archive, and include a dummy collection
.anki2 file.
The code has been tested with both deck and collection packages, but
exporting deck packages w/ scheduling info will remain disabled until
the V2 scheduler has had more testing.
with autosync on, when the progress dialog is closed and the main window
appears, it becomes stuck. hiding the dialog instead of closing it
seems to fix this.
Handle definition of context menu in same way that shortcutKeys are handled. This makes it easier for add-ons to modify the context menu without needing to re-implement the whole showContextMenu method.
qprogressdialog has been the source of a number of problems in the past,
and the most recent issue is that it's showing the progress dialog
early, regardless of what the minimum duration is set to. since we're
already using our own logic for deciding when to show the dialog, it's
easier to move to a normal dialog box
also prevent timers from firing while a progress dialog is visible, or
if the refresh timer fires we end up with the same issue.

- on Linux and Windows, opening the browser and stats window back and
forth multiple times triggers a crash in the GL libraries, even with
software rendering enabled. Will try again when .1 is out
- on Mac, shortcut keys fire multiple times:

- basic mode is the default, and includes only HTML elements that can be
added/edited easily with the default editor
- extended mode is enabled by holding down shift and includes a bunch of
other HTML elements
