ability to turn off debug sql

[adamfoneil]

An issue I run with this library is that sometimes I need to "break on all errors" when debugging, and this always breaks when resolving params due to a limitation in inspecting a Dapper DynamicParameters object. This makes it hard to debug the actual issue I'm trying to discover by "breaking on all errors." I'm trying to avoid this false positive, essentially.

What I'd like to be able to do is set a global config setting somewhere (static property) that turns debugging on and off. I would probably keep it on for backward compatibility. But if turned off, then the DebugSql would not be set.
