[PATCH 2/4] Canonicalize mirror URLs to ensure they end with a '/'

[Jon TURNEY <jon dot turney at dronecode dot org dot uk>]

This prevents a mirror URL being added twice (with and without a terminal '/')

This ensures that the download directory is consistently named, avoiding
downloading everything again, even if an additional mirror URL is added
in a form which differs in the presence of a terminal '/' from last time.

	* site.cc (init): Canonicalize mirror URLs to ensure the end
	with a '/'.
