Variable scriptlikeDryRun

Warning! This is NOT a "set it and forget it" switch. You must still take care to write your script in a way that's dryrun-safe. Two things to remember:

1. ONLY Scriptlike's functions will obey this setting. Calling Phobos functions directly will BYPASS this setting.

2. If part of your script relies on a command having ACTUALLY been run, then that command will fail. You must avoid that situation or work around it. For example:

run(`date > tempfile`);

// The following will FAIL or behave INCORRECTLY in dryrun mode:
auto data = cast(string)read("tempfile");
run("echo "~data);

That may be an unrealistic example, but it demonstrates the problem: Normally, the code above should run fine (at least on posix). But in dryrun mode, "date" will not actually be run. Therefore, tempfile will neither be created nor overwritten. Result: Either an exception reading a non-existent file, or outdated information will be displayed.

Scriptlike cannot anticipate or handle such situations. So it's up to you to make sure your script is dryrun-safe.
