Use the correct data type and MAPVK_VK_TO_CHAR constant from the WinSDK.
- small changes based on review feedback
- encode windows path to get rid of ':' before passing it as argument to the grunt task
- use system curl instead of grunt-curl to prevent out of memory error downloading the OSX symbols
- fix the download issues with Windows
- resolved issue with windows path containing spaces
- update to grunt-curl 2.0.2 which resolved the out of memory with node. This makes my interim solution obsolete.
