Ensure TextWriterAnnouncer log file is flushed and closed.
Replaced PerScriptLog (bool) with ScriptFailureAction (enum) that has more failure options.
Added PasswordFilterAnnouncer.cs to filter out passwords from logged connection strings.
Implemented IMigrationProcessorOptions.ScriptFailureAction._get in unit testing.
Removed IProfileLoader.FindProfilesIn() from interface IProfileLoader (its only part of the implementation).
Added VS2012 solution file.
