Build nightlies of others add-ons

[AntoineTurmel]

The script should be able to "build" (package an .xpi file) from other repos like:

https://github.com/nightingale-media-player/nightingale-addons There is a python script that is able to zip and put the version number on the file name.

I also have to track my original add-ons (most of them are on Google Code).

How do we store those add-ons nightlies ?

• /add-on_name.xpi -> Build them all for a specific date
• add-on_name//file.xpi -> Each add-on have dates folder

Since this is platform independent only one server is needed to "build" add-ons. Actually those are just zipped and uploaded.
