MS SQL Server sink

Heard the DotNetRocks show and noticed that there might be some good reasons to use an already existing MSSQL database as a store for the events. There was also an issue for this (https://github.com/serilog/serilog/issues/79). So this is my attempt for a sink doing this storage. Properties can optionally be included as a XML column. 
The log table script can be found here: https://gist.github.com/mivano/10429656

A sample project is included. Would love to hear your feedback, I m not a SQL guru, there might be better ways to do stuff.
