Fixed bug in writeDstWord() that was updating flags with negative data (and sadly, none of DEC's basic tests caught it)

Memory can now be explicitly "zeroed" with any byte pattern (but the default is still zero); note that memory blocks are still always zero-initialized when first created

It is now possible to re-attach or re-load the current paper tape; re-attaching means repositioning it at the beginning, and re-loading means loading it into RAM again. Note that whenever you reload a tape, it's HIGHLY recommended that you reset the machine first, too.
