Added .gitignore with extra admin folder (because django-mptt templates bug) and db file (since i'm using sqlite for now)
Add mptt shop apps, added global staticfiles/template_dirs for easy use (probably this is bad move)
Added url for main page
Added css for base template and fancy site icon (only as part of static files testing)
Added base empty template
Added main empty template view
Added ProductsGroup, Product, ProductsGroupAttribute, ProductAttribute models and custom admin classes for them. It follows task except fact what attributes has only char type. Also to add product attributes you need to save product with some ProductsGroup first.
