Changes on 09-09-15:

• Removed ancient (and pretty terrible) pre-artifact container container code from the ESTIMATE command that made it possible to estimate things you shouldn't, like people or ships.
• Severe arm injuries now affect how long it takes you to dig with manual tools. Broken arms prevent digging altogether. Powered tools are unaffected.
• Fixed a bug where asteroid kits would retrieve anchors if they had been deployed but not tied.
• Fixed several matching issues with the LOOK command during spacewalks. Please REPORT if you suddenly see anything you shouldn't see.
