fix: address build failures in some contracts (#24)

Description
===========
The build process for some contracts was failing due
to issues in certain Cargo.toml files.

Changes
=======
- Commented out `crate-type` in `Cargo.toml` files.
  There's a conflict with this setting when using
  the updated version of the Ink contract compiler.

- Added `no_main` attribute in `lib.rs`. This was
  missing in some contracts, and the updated version
  of the compiler is printing warning messages when
  it's missing.

This commit addresses issue #24
