--- Form validation function:
--- Gets a form variable "key".
--- If it does not exist: return "default"
--- If cast_number is true and "key" is not a number: return "default"
--- If valid is a table and "key" is not in it: return "default"
--- If valid is a function and returns nil: return "default"
--- Else return the value of "key"

--- Examples:
--- Get a form variable "foo" and return "bar" if it is not set
---             = formvalue("foo", "bar")
---
--- Get "foo" and make sure it is either "bar" or "baz"
---      = formvalue("foo", nil, nil, {"bar", "baz"})
---
--- Get "foo", make sure its a number and below 10 else return 5
---      = formvalue("foo", 5, true, function(a) return a < 10 and a or nil end)
