[IMP] send batch of names/comments instead of 1 by 1

[Ektoplasma]

Hi,

The code in skelenox and on the server side has been improved, in order to send a batch of names and comments per POST when skelenox starts, instead of one per POST request. Even if it is still quite long, it considerably reduces the first early actions of this IDA Python script. For now, I kept the methods push_name and push_comment of the SkelIDAConnection class and created the methods push_names and push_comments in order to send the whole thing at once. The script api_idaactions has been adapted to handle lists of values. I think the former methods could be removed for the 2.0.

I will probably update the tests scripts too.
