Do not set the HOME variable in the installer

We really should not need to set HOME globally anymore because we set it
in Git Bash in /etc/profile, and in the Git wrappers for cmd.exe.

Setting HOME caused problems, in particular when we hardcoded it to
the administrator's HOME if Git was installed using the administrator's
account.

This closes msysgit/git#119.

Add a Vagrantfile

Vagrant offers a painless way to install and use a defined Linux
development environment. We offer a Vagrantfile to that end for two
reasons:

1) To allow Windows users to gain the full power of Linux' Git

2) To offer users an easy path to verify that the issue they are about
   to report is really a Windows-specific issue; otherwise they would
   need to report it to git@vger.kernel.org instead.

Using it is easy: Download and install https://www.virtualbox.org/, then
download and install https://www.vagrantup.com/ (both are Open Source in
case you desire a more complicated installation), then direct your
command-line window to the Git source directory containing the Vagrantfile
and run the commands:

	vagrant up
	vagrant ssh

Add the .vagrant/ directory to the .gitignore file

It would not do to delete the .vagrant/ directory by mistake: it
contains all the relevant information used by Vagrant to manage the
virtual machine (e.g. to enable "vagrant ssh" to find the machine).
