Command line should allow input from STDIN

[xkahn]

Running csso at the command line should accept input from STDIN. (And help should be accessed only from csso -h.) Alternatively, running: "csso -" or "csso -i -" should accept STDIN as most UNIX binaries do.

Your included example;

Example:

$ echo ".test { color: red; color: green }" > test.css
$ csso test.css
.test{color:green}

would then become:

Example:

$ echo ".test { color: red; color: green }" | csso -i -
.test{color:green}
