Corrects Issue With Record Entries Containing All Whitespace (#5538)

Turns out the bug (#5538) covered all of the records PCs (medical, staff, and security). This ultimately adds a trim following the sanitation of every field in these computers so that an entry of " " is treated like "" and by extension cancels the editing of the field.

While I was at it I noticed the staff and security PCs allow you to change the person's name but didn't have name verification code of any sort. As such I was able to name myself "`<b>Captain <font color="red">Awesomepants</font></b>`", which, fun as it is, probably will break a million things. As such, I wrapped the field with the reject_bad_name helper.
