[Feature Request] Support Issue a Token on webpage

[jolestar]

Issue a Token on the webpage, and support some customization options, such as total issue amount, etc.

The most difficult part to achieve this requirement is: How to compile Move code on the webpage?

There are two possible approaches:

1. Compile the move compiler to WASM, and call it in javascript.
2. Support a compiler backend, the best way to do this is to provide a lambda function on AWS, for compiling Move source code to Move bytecode and Package.

@jolestar I found rust target wasm32-unknown-emscripten support FS

@jolestar I tried to compile move-compiler with target wasm32-unknown-emscripten , but I have two problems:

• undefined symbol: __gxx_personality_v0
  
  I found a solution at Emscripten wasm32 compilation broken rust-lang/rust#85821, set the environment variable before build: EMCC_CFLAGS="-s ERROR_ON_UNDEFINED_SYMBOLS=0"

• error[E0428]: the name inner is defined multiple times
  
  No good solution for now

@jolestar I found a new solution, using this wasmer-js library, and I'm verifying the feasibility.

[yubing744]

@jolestar I have verified that it works, and I have written an example to demonstrate how to use wasmer-js to compile the move module in the browser.

@jolestar Now, I have implemented Compile the move compiler to WASM, and call it in javascript. Is it possible to create a new project move-js based on https://github.com/yubing744/move-js at https://github.com/starcoinorg. Then, I will use move-js to Issue a Token on webpage.

Great! Give me permission, I transfer the project to starcoinorg.

I transferred the ownership of move-js to you.
