[Omake] adding a builtin posix-like "install" command?

[Erick Tryzelaar]

Hello again,

Would it be possible to add a builtin posix-like install function? This 
helps to collapse a bunch of common functions into one call. It 
shouldn't be too difficult to do since cp, chmod, chown, and mkdir -p 
are already built in. I'd write it myself, but I'm not sure the best way 
to implement the option flags handling like the other builtin commands.
