Visual D v0.3.43 beta 2

Changes from beta1:

• fixed calling linker to build with VC runtime of VS2015: legacy_stdio_definitions.lib missing
• bugzilla 12021: C++ projects (and others probably, too) might not load correctly in a solution
  that also contains a Visual D project
• VS2015 linker updates logs and telemetry data files, confusing tracked linker dependencies.
  Now ignoring files that are both read and written.
