Change UI config to yaml?

[Daniel Gruno]

While having a cup of coffee on the balcony, I got to thinking - would
it make sense for us to convert the PM UI configuration to yaml instead
of a .lua file? It should make it less arcane to edit for non-techies.

The config could be something like this:

# ElasticSearch settings
database:
    host:               "http://localhost:9200/";
    db:                 "ponymail"
    secure:             false

# Outgoing email settings
smtp:
    host:               "localhost:25"
    accepted_domains:
        - "apache.org"
        - "*.apache.org"

# User Interface settings
ui:
    wordcloud:          false
    slow_count:         true

etc etc :)

thoughts?

With regards,
Daniel.
