add catchall system & http pc server

- define a catchall name to run globally or per service
- catchall must be javascript, but not necessarily a .js file
- catchall can request async mode
- catchall will catch any non-existing requests under its directory
- see wtv-flashrom:/content/content-serve.js as an example, which will catch wtv-flashrom:/content/ URLs.

- http pc: sends HTTP/1.0 to PC clients
- can be disabled with `pc_server_hidden_service_enabled`: false
- can change servicevault path by changing string of pc_server_hidden_service
- get.js in default PC service vault to get any WTV Url on the service
