Update reference.md: string literals section

Browse source 
Remove the name "multi-line string literal" since the rule appears to affect each line-break individually rather than the whole string literal. Re-word, and remove the stray reference to raw strings.

A _string literal_ is a sequence of any Unicode characters enclosed within two
`U+0022` (double-quote) characters, with the exception of `U+0022` itself,
which must be _escaped_ by a preceding `U+005C` character (`\`), or a _raw
string literal_.
which must be _escaped_ by a preceding `U+005C` character (`\`).
A multi-line string literal may be defined by terminating each line with a
`U+005C` character (`\`) immediately before the newline. This causes the
`U+005C` character, the newline, and all whitespace at the beginning of the
next line to be ignored.
Line-break characters are allowed in string literals. Normally they represent
themselves (i.e. no translation), but as a special exception, when a `U+005C`
character (`\`) occurs immediately before the newline, the `U+005C` character,
the newline, and all whitespace at the beginning of the next line are ignored.
Thus `a` and `b` are equal:
```rust
let a = "foobar";
