Downloads the Junction tool from sysinternals.com to create links
Also tries to remove links first before removing them as directories to circumvent the problem of recursively deleting the brackets repository even if it is a junction.
XP support for scripts/make_symlinks.bat
@DennisKehrig - we've updated our builds to use grunt, and in the process switched from symlinks to junctions. This should fix the problems on XP.
I'm closing this pull request since it is out of date. If you get a chance, please try building on XP and let us know how it works. Thanks!
