BlockNotify support

[bonesoul]

-blocknotify= Execute command when the best block changes (%s in cmd is replaced by block hash)

we can use the internal webserver & wget to get notified.

• wget is unix only.
• so we can write a simple httpclient command line tool to do the job.
• another alternative: https://github.com/abock/CurlSharp
