Support for autocommit option

[vladg0]

I am running dbfit 3.2.0 with fitSharp 2.7.0 against SAP ASE 15.7

I am getting an error while trying to use !|set option|autocommit|true|

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ApplicationException: Unsupported optionautocommit
at dbfit.util.Options.SetOption(CellProcessor processor, String name, String value)
at dbfit.DatabaseTest.SetOption(String option, String value)

This indeed appears to be an unsupported option based on the latest code:
https://github.com/jediwhale/fitsharp/blob/master/source/dbfit/util/Options.cs

Without this feature, I am unable to test any stored procedures that utilize temporary tables and other ddl operations that don't support nested transactions.

Thank you

fitSharp includes an older version of dbfit, implemented in .NET. The Java version (http://dbfit.github.io/dbfit/) has had several enhancements that aren't in the .NET version. I don't have the time or expertise at this point to add these enhancements to the .NET version so I have to rely on contributions from others for dbfit.
