Installer: Include and deploy msvcr110.dll and msvcp110.dll

The msvcr110.dll and msvcp110.dll libraries are now included in the installer and extracted to InstallDir\Runtime\. The VC++ 2012 redistributable package is no longer downloaded and installed.

Rainmeter.exe will first try to load Rainmeter.dll normally. If it fails, it will retry after loading Runtime\msvcp110.dll. This means that our copy of the runtimes will be used only if the system copy is either not present or somehow invalid.

See Building.md for updated build instructions.
