Build with mirror

Add the following to the .cargo/config file(replacing IP with your ip).

[source.zerus]
registry = "sparse+http://[IP]/crates.io-index/"

[source.crates-io]
replace-with = "zerus"

Margo

Through the use of margo, you can make a alternate Cargo registry without downloading the entire crates.io git index.
