Admin integration

Getting a interface for viewing revision, and even changing the current head, is quite easy. Simply use RevisionedModelAdmin as such:

from django.contrib import admin
from model_revisioning.admin import RevisionedModelAdmin
from .models import Bar

admin.site.register(Bar, RevisionedModelAdmin)

Since RevisionedModelAdmin inherits from ModelAdmin, it is possible to extend the admin as usual:

from django.contrib import admin
from model_revisioning.admin import RevisionModelAdmin
from .models import Bar

class BarAdmin(RevisionModelAdmin):
    list_display = ('char', 'current_revision', 'revisions_count')

admin.site.register(Bar, BarAdmin)
