Jonathan Bernard 201556ecbe Fix vCard 3 text escaping and decoding ...

Implement RFC 2426 text escaping consistently across vCard 3
serialization and parsing.

On serialization, escape backslashes, newlines, semicolons, and commas
for simple text properties, structured text components, and list-valued
text properties so generated FN, N, ADR, ORG, CATEGORIES, and related
properties are spec-compliant on the wire.

On parsing, decode escaped text for the properties that were previously
read as raw values: FN, NICKNAME, LABEL, MAILER, TITLE, ROLE, PRODID,
and SORT-STRING. This preserves existing structured-text parsing for N,
ADR, NOTE, ORG, and CATEGORIES while fixing the direct raw-value
mismatch identified in the review.

Add regression coverage for both directions: parsing escaped text values
and serializing escaped simple, structured, and list text values.
