Commit Message

Auto merge of #786 - nabijaczleweli:feat/783-no_cargo, r=kbknapp

Add no_cargo feature to disable Cargo-env-var-dependent macros

For example, given:

```toml
clap = { path = "t:/clap-rs" }
```

The macros `crate_version!()` and `crate_authors!()` exist, so the crate compiles without errors:

```
   Compiling https v0.2.0 (file:///P:/Rust/http)
    Finished debug [unoptimized + debuginfo] target(s) in 6.93 secs
    Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs
[Finished in 7.5s]
```

But, adding the `no_cargo` feature:

```toml
clap = { path = "t:/clap-rs", features = ["no_cargo"] }
```

The macros are removed, so the crate fails to compile:

```
   Compiling clap v2.19.2 (file:///T:/clap-rs)
   Compiling https v0.2.0 (file:///P:/Rust/http)
error: macro undefined: 'crate_version!'
  --> src\options.rs:40:22
   |
40 |             .version(crate_version!())
   |                      ^^^^^^^^^^^^^

error: macro undefined: 'crate_authors!'
  --> src\options.rs:41:21
   |
41 |             .author(crate_authors!())
   |                     ^^^^^^^^^^^^^

error: aborting due to 2 previous errors

error: Could not compile `https`.
```

Closes #783
