hot-reload-bot adding hot-reloading config

[suntong]

The hot-reload-bot demo code only hot-reload event handling scripts, however, most event handling will need some kind of configuration, so it is nice to hot-reload configurations as well.

Do you already have some code exist to handle that @Gcaufy? Would you care to update the demo if you do please?

Otherwise, I'll see if I can do something, if it is OK, @Gcaufy, @zixia. But mind you, I've never written any Javascript programs before.

Thanks for your idea.

PR is welcome. :)

Ok, I'll look into it, since @Gcaufy don't have the extra bandwidth.

When asking the question, I was thinking to send in PR for the hot-reload-bot demo code, but now, after thinking it over these period, I'm planning to submit a different demo instead, It's is still based on @Gcaufy's hot-reload-bot demo, but will be much more to it, so that's the main reason. What will be included in the new demo will be a turn key solution of getting started with serious wechaty customization blue-print.

• Pure ES6 code, no Typescript, as per @Gcaufy's existing code
• All even handling, as per @Gcaufy's existing code
• Hot-reload even handling code, as per @Gcaufy's existing code
• Hot-reload configurations as well
• emoji cleansing -- to simplify emoji from <img class="qqemoji qqemoji13" text="[呲牙]_web" src="https://wx.qq.com/zh_CN/htmledition/v2/images/spacer.gif" /> to merely [呲牙]
• Auto-save all media files, i.e., incorporate media-file-bot.ts into this getting started demo
• Graceful exit on SIGINT/SIGTERM, i.e., to write key info into file, on receiving killing signals (e.g., SIGINT (2), SIGTERM(3)), before termination, so as to do a "graceful shutdown".

All in all, it's be a true solution for people to get started using wechaty, a one-stop demo for people to get an easy start.

oh, on seeing the issues in

• Fix #923 #935, and
• emoji suggestion #1108

I realize that I'm not anywhere near the position to provide such demo...

[suntong]

OK. work started, ref: https://github.com/suntong/wechaty/commits/m1
which will eventually be merged back (after I'm done)...
