[PD] Pass arg to Pd via terminal

[Christof Ressi]

Actually, I've thought if we could use a semicolon to seperate patch 
from arguments:

pd -open "mypatch1.pd; 1 2 3" -open "mypatch2; foo bar"

Unfortunately, semicolons are not really reserved characters for 
filenames, neither on Windows, nor on Linux/macOS, but their use is 
certainly discouraged.

On the other hand, colons are forbidden characters on Windows and macOS, 
but not on Linux. This means they are not 100% safe, but maybe better 
than semicolons. On Pd we don't need to delimit every argument (because 
arguments are already delimited by spaces), so a single colon between 
patch name and arguments would be sufficient:

pd -open "mypatch1.pd: 1 2 3" -open "mypatch2: foo bar"

Personally, I like this more than using "stateful" command options like 
"-args".
