Add JSON API

[dsbaars]

As described in #15 , I added JSON API calls using jansson and rewrote the dashboard HTML pages to consume the API's. These pages now automatically update as well.

It is stil quick and dirty but at least now there is a usable API for monitoring and integration with other applications.

Home

/api/v1/stratum_server_info
/api/v1/client_stats (might be better named gateway stats?)
/api/v1/current_stratum_job

Clients

/api/v1/clients

Threads

/api/v1/threads

Coinbaser

/api/v1/coinbaser

But now the web interface requires Javascript :(

What do you think of something like #21 ?

It already required JavaScript for the killing/disconnecting of stratum clients...
Doing a HTTP request for each property doesn't seem very efficient, but it does the job.
It looks like your solution works for just for the homepage but not (yet?) for client/thread statistics, and to make those machine-readable I don't see a way other than JSON/MsgPack.

I'm not a fan of requiring javascript for the dashboard, but it's great if it functions wo/javascript and is augmented by javascript for updating data wo/refreshing and such.

Fixed in #25 :)

@dsbaars Any thoughts on #25? Or would you prefer to rebase this (maybe without the JS requirement)?
