Use G_DECLARE_DERIVABLE_TYPE for PurpleConversation and additional cleanups

Use G_DECLARE_DERIVABLE_TYPE for PurpleConversation and additional cleanups

The setters for PurpleConversation are kind of crappy because of the
conversation cache in the purple_conversations api, which we'll address at a
later time.

Testing Done:
Compiled and ran locally, parted a chat and just signed out to verify no new issues.

/**
* PurpleProtocolClientInterface:
* @get_actions: Returns the actions the protocol can perform. These will show
* up in the Accounts menu, under a submenu with the name of the
* account.
* @list_emblem: Fills the four <type>char**</type>'s with string identifiers
* for "emblems" that the UI will interpret and display as
* relevant.
* @status_text: Gets a short string representing this buddy's status. This
* will be shown on the buddy list.
* @tooltip_text: Allows the protocol to add text to a buddy's tooltip.
* @blist_node_menu: Returns a list of #PurpleActionMenu structs, which
* represent extra actions to be shown in (for example) the
* right-click menu for @node.
* @buddy_free: Allows the protocol to clean up any additional data for the
* given buddy.
* @convo_closed: Allows the protocol to do any necessary cleanup when a
* conversation is closed.
* @normalize: Convert the username @who to its canonical form. Also checks for
* validity.
* <sbr/>For example, AIM treats "fOo BaR" and "foobar" as the same
* user; this function should return the same normalized string for
* both of those. On the other hand, both of these are invalid for
* protocols with number-based usernames, so function should return
* %NULL in such case.
* <sbr/>@account: The account the username is related to. Can be
* %NULL.
* <sbr/>@who: The username to convert.
* <sbr/>Returns: Normalized username, or %NULL, if it's invalid.
* @find_blist_chat: Attempts to find a chat with the given name in the contact
* list.
* @offline_message: Checks whether offline messages to @buddy are supported.
* <sbr/>Returns: %TRUE if @buddy can be sent messages while
* they are offline, or %FALSE if not.
* @get_account_text_table: This allows protocols to specify additional strings
* to be used for various purposes. The idea is to
* stuff a bunch of strings in this hash table instead
* of expanding the struct for every addition. This
* hash table is allocated every call and
* <emphasis>MUST</emphasis> be unrefed by the caller.
* <sbr/>@account: The account to specify. This can be
* %NULL.
* <sbr/>Returns: The protocol's string hash table.
* The hash table should be destroyed
* by the caller when it's no longer
* needed.
* @get_moods: Returns an array of #PurpleMood's, with the last one having
* "mood" set to %NULL.
* @get_max_message_size: Gets the maximum message size in bytes for the
* conversation.
* <sbr/>It may depend on connection-specific or
* conversation-specific variables, like channel or
* buddy's name length.
* <sbr/>This value is intended for plaintext message,
* the exact value may be lower because of:
* <sbr/> - used newlines (some protocols count them as
* more than one byte),
* <sbr/> - formatting,
* <sbr/> - used special characters.
* <sbr/>@conv: The conversation to query, or NULL to
* get safe minimum for the protocol.
* <sbr/>Returns: Maximum message size, 0 if unspecified,
* -1 for infinite.
*
* The protocol client interface.
*
* This interface provides a gateway between purple and the protocol.
