UserOperation_fix_tshirt_size_request view: first implementation

Browse source 
The `UserOperation_fix_tshirt_size_request` view is designed to allow
end-users edit t-shirt sizes in the request using a program like
`sqlitebrowser`.

This is the first implementation attempt of a user operation that
allows changing the T-Shirt size.
