Monkey patching shell provisioner for windows

This commit adds monkey_patches to make shell provisioner to work
on windows.

Fix mkdir parameter
mkdir parameter did not work properly
Bump version to 1.0.3
Added win_friendly_path method to convert unix style paths to windows style paths
Updated gemfile and lock to point to vagrant 1.1.5, since later versions are incompatible
Use the builtin vagrant source_root path for finding the vagrant folder. This is more reliable, works with bundler, and reduces duplication.

Modified the shell provisioner to support inline scripts.
Updated readme for shell provisioner
Merge pull request #46 from WinRb/pr/45

Shell provisioner support
Dont advice the users to forward the port for RDP

... because it breaks VRDE extension of VirtualBox. When you switch on VRDE to be able to connect look on your VM's via RDP viewer, VB offers an according port *on the host*, already. No need to make port forwarding.

Add optional instruction to make WinRM start faster

In windows 2008 and Windows 7, the WinRM service defaults to start delayed-auto. In my environment this blocks Vagrant for 2.5min. Setting service to start "auto" reduces this delay significantly.
