Get bitbucket to work with git-bash on Windows

Add public key to bitbucket account setting SSH keys.

On Windows, add a System environment variable:

GIT_SSH -> C:\Program Files\PuTTY\plink.exe

Run peagent.exe, load the private key.

At the first time, run putty, enter git@bitbucket.org, then open, cache the key.

Now key is cached, we can run git clone from git-bash without problem.
