I added one template for manual entry of noun declensions and one automatic.
You can see how to use them in the муха word http://masterrussian.net/wiki/%D0%9C%D1 ... Declension

Automatic template for words grammatically similar to муха require just one line to generate a complete table:
{{ru-noun-anim-vel-а-1|мух|му́х}}

I am going to add more automatic templates when I figure out how to use them.

I'll enable uploads a bit later.
