Provide an option to run commands via sh -c
The new flag "shell" instructs pies to run the command marked with it
as '/bin/sh -c $command'. Alternative shell can be supplied ising the
'program' statement.
This is useful if the command line uses shell-specific features (command
or variable expansion, redirection, pipes, etc.)
This commit also fixes a bug in the 'env' statement handling: a single
argument with embedded whitespaces was undergoing word splitting and
thus incorrectly handled as multiple arguments.
