[Orgmode] Command names are now in the manual

[Carsten Dominik]

Hi,

I have just added the last command missing names to the manual.  So if  
you compile the manual in the latest git version, you will find  
command names listed for almost all keys listed in the manual, along  
with a much extended command and function index.

If you do not like this change, you can compile the manual without  
command names by turning off the

    @set cmdnames

flag in the manual, using this line instead:

    @unset cmdnames

Many thanks to Andreas Röhler who kicked off this project and did part  
of the work.
