Subject: [PATCH] Build script for Windows. (#3481)

A re-implementation of build.sh for Windows ala PowerShell.  This is as

+    .Synopsis
+    Build script for Packer.
+
+    .Description
+    Build script for Packer for all supported platforms and architectures.
+    By default the following OSs and architectures are targeted.
+
+    OS:
+     * linux
+     * darwin
+     * windows
+     * freebsd
+     * openbsd
+
+    Architecture:
+     * 386
+     * amd64
+     * arm
+
+    If the environment variable PACKER_DEV is defined, then the OS and
+    architecture of the go binary in the path is used.
+
+    The built binary is stamped with the current version number of Packer,
+    the latest git commit, and +CHANGES if there are any outstanding
+    changes in the current repository, e.g.
+
+      Packer v0.10.1.dev (3c736322ba3a5fcb3a4e92394011a2e56f396da6+CHANGES)
+
+    The build artifacts for the current OS and architecture are copied to
+    bin and $GOPATH\bin.
+
+    .Example
+    .\scripts\build.ps1
+#>
+
+# This script builds the application from source for multiple platforms.
+
+# Get the parent directory of where this script is.
