CocoMUD client

So far, the updater has a really straightforward mechanism:

• It checks on the Planio website, to see if the current version of the client is not the most recent one.
• If it finds a more recent version on the website, it offers the user to download it.
• Once downloaded, the new version is unzipped in a sub-folder.
• Then the updater shuts down and gives command to a simple BAT script that will replace all folders (except the user settings) in the main folder.
• This script will then launch the new version of CocoMUD.

The script runs in a command window that is clearly visible to the user. Although no big deal in itself, it's ugly and could be changed. See here for an example:

from subprocess import popen
hidden = 0x08000000 # Windows only
Popen(["script.bat"], bufsize=-1, creationflags=hidden)
