Subject: [PATCH] Add environment variable to block individual ecloud
 expansions.

This commit adds the environment variable "PAPI_BLOCKED_EXPANSIONS"
which can contain a case insensitive, comma separated list of blocked
expansions.
Expansions on this list can no longer be downloaded using commands.
