Improve error reporting: message when defining record with open brace on separate line

# what

When defining a record (and being used to brace languages):

```fsharp
type Foo =
{
bar: int
}
```

F# yields

>A type definition requires one or more members or other declarations. If you intend to define an empty class, struct or interface, then use 'type ... = class end', 'interface end' or 'struct end'.

# why

I made a "mistake" of putting `{` on its own line without indenting it

# how

I'd like the compiler to tell me how to fix the record definition:

> The record definition is invalid due to erroneous indentation, either put the opening brace on same line as type declaration or make it indented.

Note that for C# and VB.NET users (and even more for Resharper users), they'd expect the editor to be helpful with formatting, if I open `{` after `type Name =`, it should probably indent or put the brace back to the type declaration line.

I do get rants from C#/VB.NET developers about how F# editor in VS doesn't format the code while being typed and how it makes F# "unusable".
