On listing documents,gates,etc. the elements should be indented in the terminal display

[d4r3topk]

The current layout is 2 spaces after every element. This occurs in steam-shell.pike on executing a list command or look command. Eg. "list gates", "look". The elements are not properly indented. They need to be indented in the manner, how the "ls" command works on UNIX.

#26 Fixes this.

#26 has a solution which takes into consideration the default screen size of a linux terminal.
Default column size is 80, but if it is modified by the user then the output is not properly indented.
