NETSCRIPT: Add additionalMsec to BasicHGWOptions

This option adds additional time to the sleep in hack/grow/weaken before
the command takes effect. The critical difference between this and doing
your own sleep is that it creates a single, uninterruptible sleep: This
opens up multiple new avenues of gameplay for batching.

Note that use of this new feature is theoretically always suboptimal,
since extending the sleep time wastes RAM.
