Technical issues

Trying to add support for native DataChannels on Chromium v26 I have had some problems in the last days and ShareIt! was not working correctly, so after going back and fixing it I decided to do a Draconian decission: no more references to external libraries, and use instead a local copy. I know this would break one of the points of the Universitary Free Software Championship (re-use existent code), but the fact is that the external libs are all in an unique place (the /lib folder) so it can be easily upgraded, and also this has several advantages, like being sure to have a working version all the time since it's being used an expecific version of the libraries, being easier to deploy on any other place, and since all the code is auto-contained now I don't require to add some special permissions on the FirefoxOS manifest file, so users don't need to worry about them. This also has lead me to isolate the usage of the EventTarget.js library only to WebP2P, so now the UI uses exclusively jQuery events, making it more straigforward to develop and to use less memory usage. Now it only keeps to finish a script I'm working on to update all the external libraries at a time, so the fact of being the libraries inside the source code tree or as external libs would be indiferent.
