Add support for changing the debug information for Visual Studio 2017 files to DebugFull. The default for VS2017 (i.e. when debug information is set to 'true') is to use fastlink. There is a new option to use a full pdb file. For older versions of Visual Studio, the new 'Full' symbols option behaves like 'On'. (#694)
