Revert "core.runner: removed 's', 'p', 'w' flags to behave like rifle"

It makes ... little sense atm to remove this.

 Example:

 run('sleep 2', wait=True)         # waits until the process exists
-run(['ls', '--help'], flags='t')  # runs in a new terminal
+run(['ls', '--help'], flags='p')  # pipes output to pager
 run()                             # prints an error message
 
 List of allowed flags:
+s: silent mode. output will be discarded.
 f: fork the process.
+p: redirect output to the pager
 c: run only the current file (not handled here)
+w: wait for enter-press afterwards
 r: run application with root privilege (requires sudo)
 t: run application in a new terminal window
 (An uppercase key negates the respective lower case flag)
