Make the image footer optional

[sluongng]

This is a very cool package.

It would be a lot easier to adopt if you make the footer(twitter/wechat) optional.

Better yet, provide a config for user to either turn off the footer or customize their own during deployment.

Is it ok to add a -simplefooter option, if which is specified, a simple footer like "Generated with Golds v0.1.7. (GOOS=linux GOARCH=amd64)" is used instead?

[sluongng]

Yeah something like that would be much preferable.

Just keep in mind that people can always make a fork and change up the code. But having a customizable options would make it easier to use the current package as-is.

@sluongng
Thanks for the suggestion.

The project will use a configuration file to customize generation outputs when most of planned features are implemented and most command line options are stabilized. Since then, local go.lds files and a global one will be looked up and viewed as configuration files. (I opened another issue for this.)

Currently, (experimental) command line options are preferred. Forks are welcome if these options don't satisfy specific needs.

A -footer option will be added soon afterwards.

A -footer-showing=verbose+qrcode|verbose|simple|none cli option is added in v0.1.8.
