Quote rangevars to support special from clauses

[avinoamr]

Similar to #40 . Currently, deparsing special/unsupported from clauses results in incorrect SQL code:

select * from "hello-world"

will deparse into

select * from hello-world

Where the dash is unsupported.

Fixed by quoting all rangevars.

@avinoamr I didn't release a new gem version yet - I'll do that tonight 👍

@lfittl Is it done? I didn't see a new tag.
