Adds basic support for joining MUCs― so basic that Caya won't even tell
the user they've joined, and messages can't be received.
The scaffolding for further MUC development was added, and some
much-needed error-handling for stanzas has been created.
The roster list is now split from MainWindow into RosterWindow, which
can be used arbitrarily for selecting something from contacts. The
im_what, title, and target can be specified.
Right now it's in use under the Chat menu, "New chat…". Chats can only
have two members (DM/PM), so "New chat…" directly leads to the roster
list.
In the future, roster list might be extended to allow specification of
non-contact users based on their identifiers, or filtering based on
protocol/account― this could help it with "invites" to future rooms,
etc.
IM_CREATE_CHAT and IM_CHAT_CREATED were also added to the protocol API,
allowing a new chat to be explicitly created from Caya or the protocol.
This is a commit with it's foot in a lot of places, but:
The Conversation class was created as the abstraction of chats: All
ImMessages that are relevant to a conversation get routed through it,
meta-data on chats is stored in it (even if right now that's basically
limited to the user list and ID).
Server was given more methods to help accessing contacts―
ContactById(BString) and AddContact(Contact*). This better allows
Conversations to add and fetch Contacts as necessary. Right now, all
users in chats are treated as Contacts, so in the future creating an
independent userlist for Server (fUserMap?) would be useful.
Server also now stores all Conversations (fChatMap) and has some
convenience methods like for Contacts: Conversations(),
ConversationById(BString), and AddConversation(Conversation*).
CayaRenderView has been changed to not store user nicks, and will use
the appropriate nick of any arbitrarily-numbered user.
Users also have a map of all Conversations they are a part of
(fChatMap).
The Remove* methods of KeyMap now return the removed item.
Now an add-on can contain multiple protocols, and the protocol API has
changed. An add-on must now export protocol_count() and protocol_at(),
with the latter replacing protocol(). protocol_count() returning the
amount of protocols in a given add-on, and protocol_at(i) giving a
new CayaProtocol* "at" the given index.
CayaProtocol has also been changed, adding Signature(),
FriendlySignature(), Icon(), Path(), and SetPath(). The reasoning is
that different protocols (even within a single add-on) will have
different signatures and icons, so this data should be accessible from
the protocol itself.
CayaProtocolAddOn now has CountProtocols() and ProtocolAt(i), allowing
the accessing of multiple protocols. A CayaProtocolAddOn can be given a
default protocol index in the constructor, whose protocol will be
returned with Protocol(). Version() was also moved from CayaProtocol to
CayaProtocolAddOn.
