VCard does not escape semicolons per RFC 2426

{{{

from pyxmpp.jabber.vcard import VCard, VCardName
v = VCard('')
n = VCardName('N', '')
n.given = 'Christopher; a semi-colon and a sentence, too.'
v.content['N'] = n
v.as_xml().serialize()
'\nChristopher; a semi-colon and a sentence, too.\n'
xml = [c for c in v.as_xml().children][0] #list comprehension to compensate for \nChristopher; a semi-colon and a sentence, too.Christopher; a semi-colon and a sentence, too.\n'
v.rfc2426()
'begin:VCARD\r\nversion:3.0\r\nn:;Christopher; a semi-colon and a sentence, too.;;;\r\nend:VCARD\r\n'
v3 = VCard(v.rfc2426())

}}}

since the semicolons are not backslash escaped, nor unescaped, string values with ';' in them cannot be handled properly.

a regex which can be used to properly split strings with escaped semicolons using a negative lookbehind assertion:
{{{non_quoted_semicolon_re=re.compile(r'(?<!);')}}}

I'll append patches and such as I finalize my fixes.

(In [711]) - properly escape semicolons in structured name fields (patch by Stelminator
plus a unit test). closes #21
