IM addresses in contacts should have a "service" field, rather than a "protocol" one

[Nicola Larosa]

Currently, IM addresses in contacts have a "protocol" field. They should instead have a "service" one, because the user is not interested in the protocol, but rather in the service chosen. For example, both Jabber and GoogleTalk use the XMPP protoco, but the user knows them with the service names, and is interested in telling them apart.

For that reason, once the name of the field changes, the values should change too. Here is possible list, derived from the Kopete IM program (not sure about some of them, though):

aim, bonjour, facebook, gadu_gadu, google_talk, groupwise, icq, jabber, meanwhile, qq, sms, skype, msn_wlm, winpopup, yahoo, other

The specs on freedesktop.org should also be updated accordingly.
