Selector: Detect incorrect escape handling by old Firefox

Browse Source 
According to:
https://www.w3.org/TR/css-syntax-3/#ident-token-diagram
the escape doesn't need to be followed by a whitespace only if it's not a hex
digit or a newline. However, old Firefox (3.6 - 5 only) doesn't throw if an
escaped newline is not followed by a space. Fallback to Sizzle in such cases.

Fixes gh-454
Closes gh-456
