Volume sort numbers wrong

[Alessandro Nakamuta]

When we edit or create a new film, the volume combobox appears:
1 10 11 12 ... 19 2 20 21 ... 29 3 30 etc.

i think i would sort volumes in human readable form if instead of writing value '1' to database griffith writes values'00001' ( zeros at the beginning of the value - something like zerofill in mysql but i dont know if sqlite has some kind function)

[Piotr Ożarowski (piotr)]

what if volume/collection name is not a number? (otherwise it would be easy to sort by simply casting to integer)
