Release v0.1.0

  Tired of cleaning crates manually? Don't manually, use Rustpan!

Assuming you store you're rust project's like so...

dev/
    rust/
         crate1/
                src/
                target/ <= We know if target exists, 'cargo clean'
         crate2/
                src/
                <= If target doesn't exist, continue
         major_project/
                       sub_crate1/
                                  src/
                                  target/
                       sub_crate2/
                                  src/
                                  target/

The above will be cleaned:

dev/rust/crate1
dev/rust/major_project/sub_crate1
dev/rust/major_project/sub_crate2
