Summary:                    [patch] Improve realtime queue logging
Description: 
I was playing with the RT queue log functionality, and found this
limitations:

1. If you choose RT queue logging, you won't have the traditional plain
text file file log. This file is very useful for backup purposes.
2. The column 'data' stores all the parameters separated by '|', which is
not the best way to store it.

I managed to program a patch which overcomes this limitations, and works
this way:

1. If you enable RT queue logging, the queue log will still be logged in
the plain text file, so you have some backup in case of some database
disaster.
2. The parameters are now "exploded", and put in separate fields for each
one. The only thing here is that this code must be changed in case that
some queue log event delivers more than 4 parameters (the only event that
gives 4 parameters is TRANSFER).
3. The calldate is now stored just like the CDR, with a full datetime.
4. The plain text file is left as is, for compatibility purposes.
5. The fieldnames on the table changed a little.

Okay, I think I have a solution for this problem, and it got deeper and
deeper, while I explored the situation.  What I've done to fix the problem
is to create two logger initialization functions, the second of which runs
after the preload of modules is done.  I additionally decided that mention
of a realtime driver in extconfig should force that module to be preloaded
as a requirement.  And, as a consequence of all this, preloaded modules may
now additionally request that certain modules be loaded at a
somewhat-preload time (prior to the bulk of the modules, but after the
initial set).
