Add scaffodling support for arbitrary roles and permission-based (and
varying!) UI.
A new class, Role, represents a user's role in a given room, with three
values:
* The role's title
* The role's permission-set
* The role's priority
The permission set is a bitmask value for various permissions (e.g.,
PERM_WRITE, PERM_BAN, etc), and priority is position in the hierarchy.
A user with higher priority (and PERM_BAN) can ban a user with lower
priority, but not vice-versa. Two users with the same priority can't
ban/kick/mute each other, etc.
These permissions should be used to determine what UI elements are
displayed― if the user doesn't have permission to ban users, then a
"Ban" button shouldn't exist. If the user is muted, they shouldn't be
able to type. So on and so forth.
For now, permissions are sent with a IM_ROLECHANGE message and stored
by the Conversation, but aren't really in use yet.
This system should be flexible groundwork to account for the varying
administrative hierarchies and norms of different protocols.
UserListView and UserItem were added as the backbone of the user-list,
and the (currently unused) Caya message CAYA_SEND_INVITE was established
for inviting users to rooms.
Some menus were reworked (e.g., pop-ups of the RosterListView) or
generally tweaked to be more sensical or consistent.
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.
This dichotomy is useful and necessary in multi-user chats, so I split
Contact into a parent class, User. User should be used for generic
members of rooms, Contact used mainly with the roster.
