getUser fix, params support, getOEmbed(), reference fixes

getUser was passing username instead of userid. Any function returning
a list now takes params parameter to put limits on the list, getOEmbed
implemented, caminte had some broken references for .next calls that
were fixed.
notsilent option, update param parameters, getUserSubscriptions(), getChannelSubscriptions(), getFollows(), getConfig(), getOEmbed()

Params were brought in sync with new definitions and fix local
incorrect ones. Added a slew of function stubs.
/config and /oembed implemented
New models config sample

Model config file is separate as changed will likely rebuild a database
