[PATCH] Add more curl options to git-http-pull

[Darrin Thompson <darrint@progeny.com>]

All,

This patch makes git-http-pull work with basic http auth and ssl when
you aren't using a real cert.

Also, it makes curl's verbose output available, which is useful for
debugging.

Apologies as I expect my mail client is munging this patch slightly.

Create option to turn off ssl peer verification.
Create option to provide username:password to curl.
Make -v additive.
When -v is specified twice, turn on CURLOPT_VERBOSE.
