Install to a subfolder

[kylechine]

Summary

I'm planning to install two Postleaf instances to

• blog.mydomain.com/en
• blog.mydomain.com/zh

for my English blog and Chinese blog respectively.

After installation and configuration (Nginx as the reverse proxy). I found there are a lot of absolute references hard-coded in Postleaf, which prevents my instance work properly.

Expection

I thought in .env, APP_URL should be a full web-access URL (instead of just https://example.com/), and used to compose internal references.

Thanks for your wonderful work.

Steps to Reproduce

1. Install Postleaf
2. Configuration
3. Access from browser.

Additional info

• Postleaf version: 1.0
• Node version: 8.11.1
• Operating system: Debian 9

This isn't currently supported. I would welcome a PR to allow this but it's going to take some effort :)
