Add the ability to check out a single file from a repo.
The syntax is:
deps {
'path': File('http://svn..../path/file@42')
}
This will checkout a single file and use scm.update to
keep it up to date.
See https://bugs.webkit.org/show_bug.cgi?id=36578#c7 for a
description of why I want to add this.
