Title: Add sshpass opt to rsync_project

for example `upload_project` can use env.password to connect to remote server. but `rsync_project` need to enter the password again. I think this is very inconvenient, it also limits the things that I found could solve this problem by [sshpass](http://sourceforge.net/projects/sshpass)
