default_ttl and default_hide read in as strings, not ints from conf file

[Tony Wooster]

Using the default burrowd.conf file, as provided with burrow, meaning that the server is loaded with a wsgi frontend and a sqlite :memory: backend, attempting to create a message causes the server to error.

Output follows (conf modified for port 8081 due to conflict):

As far as I can tell, this results from wsgi lines 71/72:

        self.default_ttl = self.config.get('default_ttl', DEFAULT_TTL)
        self.default_hide = self.config.get('default_hide', DEFAULT_HIDE)

Where these should be:

        self.default_ttl = self.config.getint('default_ttl', DEFAULT_TTL)
        self.default_hide = self.config.getint('default_hide', DEFAULT_HIDE)
