[Vimcdoc-translate] usr_toc.txt finished

[lang2 <wzh...@po...>]

Hi all,

I've finised and checked in the usr_toc.txt. You don't have
to review it now. But when you come to translate parts of
the Vim documents, please do refer back to this file and 
look for the names of the sections you will be translating 
and make sure that we have the same. 

rgds,
