Add a custom error message for values without attributes in a record

[cassiebeckley]

This implements part of the feature request in #436. It adds a slightly friendlier error message that appears when a value without an attribute in a record. For example, this code

search
  twenty = [-20]
bind
  [#ui/text text: twenty]

will generate the error message "-20" needs to be labeled with an attribute.

After this, the attribute rule could be modified to take another argument specifying whether the record that is being parsed is part of a functionRecord. If so, the message could mention that function syntax requires arguments to be labeled, and include parameter names if it is a standard library function. I can work on that next, if this looks good to you.

I'm working on the other part of this, but how do I test it out? Is there a way to get the eve-starter to run my modified code?

Hey @ChristopherDumas,
You should be able to build eve from source code by running npm install && npm run build within the eve repository assuming you have a relatively recent version of NodeJS and NPM installed.

You can then start this locally build version using npm start.

Awesome, thanks.
