DifficultyTag's aren't sorted

[metenn]

Seems like somebody forgot ordering = ['pk'] in Meta

oioioi/oioioi/problems/models.py

Lines 818 to 838 in 5414a6c

	class DifficultyTag(models.Model):
	name = models.CharField(
	max_length=20,
	unique=True,
	verbose_name=_("name"),
	null=False,
	blank=False,
	validators=[
	validators.MinLengthValidator(3),
	validators.MaxLengthValidator(20),
	validators.validate_slug,
	],
	)
	problems = models.ManyToManyField(Problem, through='DifficultyTagThrough')
	class Meta(object):
	verbose_name = _("difficulty tag")
	verbose_name_plural = _("difficulty tags")
	def __str__(self):
	return str(self.name)

same goes for DifficultyTagLocalization, which is why this code returns unsorted rows (per SQL specs rows are not automatically sorted by any field)

oioioi/oioioi/problems/views.py

Line 556 in 5414a6c

for tag in DifficultyTagLocalization.objects.filter(language=get_language())

so another fix would probably be adding an .order_by() here?

perhaps the ordering should be more explicit in the first place rather than relying on the autogenerated pk field?

As a bonus:
Seems like the styling on these buttons is a bit broken, not to mention the inconsistent heights.
