SteamPipe VDF Builder & Upload Dry-Run Assistant

How it works
VDF is serialized with tabs like typical KeyValues. Validate IDs in Steamworks.
app_build.vdf
"AppBuild"
{
"appid" "480"
"desc" "CI build"
"contentroot" "D:\\\\build\\\\content"
"buildoutput" "D:\\\\build\\\\output"
}depot_build.vdf
"DepotBuild"
{
"DepotID" "481"
"ContentRoot" "D:\\\\build\\\\content"
}- Validate IDs in Steamworks; paths must exist on the build machine.
