[WIP] Draft implementation of python server.

[wapiflapi]

This is a draft for a server in python. It uses flask and the standard shelve module to store info instead of sqlite.

It needs serious testing. The protocol has been changed to be more restful. (#13)

This is a PoC. Some known problems:

• The settings are hardcoded and should be in the configuration file.
• By default they should be relative as they are for the PHP version.
• The dates returned by the server are not converted to the correct timezone uppon display.
• Rewrite the tests without relying on the sqlite database.

We need to update the tests as well. This isn't as trivial because curently they rely on the sqlite database which is no longer used in this version.
