Support for reserved characters and whitespace in selectors

[sdeming]

I have a use case where I have to generate SQL queries where some columns have spaces embedded.

Simplified Example SQL:
SELECT * FROM dbo.Movies WHERE [Movie Title] = 'TRON'

This would be created from the following RSQL:
"Movie Title" == TRON

I propose that you can use the same grammar for selectors that is already used for arguments, that is, you can allow unquoted with only unreserved characters or a single or double quoted string, unescaped.
