File transfer handler

[Daniele E. Domenichelli]

Since the filetransfer-uri branch was merged in tp-qt4 and now the URI
property can be used for file transfers (see [1]) I pushed the file
transfer handler in a scratch repository, you can clone it from here
[2]. I also sent a request for an official repository in
playground/network/telepathy where I would like to move it...

You will need the last git version of tp-qt4 to build it and it will
officially support tp-qt4 >= 0.7.1

Since people usually don't read the README file I'll just copy/paste the
important part here:

-------

WARNING: At the moment it just works for incoming file transfers and
         will overwrite any file in the $HOME/Download directory which
         has the same name as the file that you are receiving, so
         please ensure that you don't have any valuable file there.

You can modify the download directory by adding in your
.kde/share/config/ktelepathyrc file in the section [File Transfers] the
variable downloadDirectory

[File Transfers]
downloadDirectory=<download path>

-------

At the moment only incoming file transfers works and only sometimes.
Gabble crashes on outgoing file transfers and I cannot figure out why,
therefore I reported a bug here [3], but I'm not sure if it is a problem
of gabble I am doing something wrong..

Together with the file transfer handler you will find a new
"filetransfer" branch on telepathy-contact list that will set the URI
property for the ft channels and on my scratch repository [4] a quite
bugged version of the approver that supports file transfers.


Cheers,
 Daniele
