downloads: add initial handling for downloads

We are using json as a format to store our download information
as the format is rather simple and can be parsed without problems
and dependencies.

from django.db import models
from django.utils import simplejson

def get_download(platform, version):
    '''get the download for the right version'''
    f = open('downloads.json')
    list = simplejson.load(f)
    f.close()
    latest = version == 'latest' or not version
    for entry in list:
        if (latest and entry['latest'] == 'true') or entry['version'] == version:
            for version in entry['versions']:
                if version['identifier'] == platform:
                    return version['url']
def get_latest_version():
    '''return the latest available version'''
    f = open('downloads.json')
    list = simplejson.load(f)
    f.close()
    for entry in list:
        if entry['latest'] == 'true':
            return entry['version']
