mod_carbons_copies: Initial commit; allow the user to enable v0 style carbons
for clients which are not carbons-capable yet. This will not interfere with
clients which have support for regular Message Carbons (XEP-0280).
This module takes two optional parameters:
carbons_copies_default - if set to true, copies will be enabled by default
carbons_copies_adhoc - Enable Adhoc-commands to allow the user to
enable/disable copies

| 1 -- Send carbons v0 style copies of incoming messages to clients which | |
| 2 -- are not (yet) capable of Message Carbons (XEP-0280). | |
| 3 -- | |
| 4 -- This extension integrates with the mod_carbons plugin in such a way | |
| 5 -- that a client capable of Message Carbons will not get a v0 copy. | |
| 6 -- | |
| 7 -- This extension can be enabled for all users by default by setting | |
| 8 -- carbons_copies_default = true. | |
| 9 -- | |
| 10 -- Alternatively or additionally setting carbons_copies_adhoc = true | |
| 11 -- will allow the user to enable or disable copies through Adhoc | |
| 12 -- commands. | |
