Alex Crichton 8caa5a9476 Spice up the project README, fill out more docs (#1010) 
* Spice up the project README, fill out more docs

This is an attempt to spruce up wasmtime's README.md file as well as
fill out more of the missing documentation in the `docs/` folder.
There's still a long way to go but I hoped here to mostly move around
existing information and add new information. As always happy to have
feedback!

* Tweak CLI wording

* Remove no-longer relevant clause

* Update sandboxing docs

* Handle comments

Using the wasmtime CLI

In addition to the embedding API which allows you to use Wasmtime as a library, the Wasmtime project also provies a wasmtime CLI tool to conveniently execute WebAssembly modules from the command line.

This section will provide a guide to the wasmtime CLI and major functionality that it contains. In short, however, you can execute a WebAssembly file (actually doing work as part of the start function) like so:

$ wasmtime foo.wasm

Or similarly if you want to invoke a "start" function, such as with WASI modules, you can execute

$ wasmtime --invoke _start foo.wasm

For more information be sure to check out how to install the CLI as well as the list of options you can pass.
