detect if cargo toml has wasm-bindgen dep

[ashleygwilliams]

this issue is reserved for someone who has not yet contributed to wasm-pack

---

in order to compile to wasm32-unknown-unknown, the user must put the following in their Cargo.toml:

[dependencies]
wasm-bindgen = "0.2"

we have the ability to check this before we try to compile- to save the user some time and help remind them to do it!

we'll probably want to work on this in the manifest.rs file, and it might be similar to the get_crate_name function... see here

I'd love to tackle this one if it's ok for you!

[ashleygwilliams]

@robertohuertasm you got it! let me know if you want any help!

Do I have to check the version? If that's the case, must "0.2" be the minimum version or it has to be fixed?

[ashleygwilliams]

@robertohuertasm i think for the moment we should just check that the dependency is present. the version portion is a bit more complicated and something we'll deal with when we resolve #146
