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

Fixed zeroMemory() to properly zero any block(s) that originally underlaid the IOPAGE block(s), rather than trying to zero the IOPAGE block itself (which would be a bad idea)

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.

Fixed stepCPU() so that, if a Debugger is present, it always calls checkInstruction() on at least the first instruction of a run, so that Debugger features like skipping over an initial HALT opcode works properly

Added getTrapStatus() so that the Debugger can display trap information whenever a trap has just occurred, updated FileDump to store 'load' and 'exec' properties in MACRO-11 listing dumps (so that the individual machine files don't have to specify hard-coded 'load' and 'exec' values themselves), and added a new SerialPort parameter (upperCase) that can be used to force all received data to upper-case
