Some test updates.

* I added a relative branch that just exceeded the +127 range.  This
  did expose a bug related to the fact that the error was reported
  during both passes and a phasing error since it generated code on
  the first pass (because of potential forward reference effects) but
  not on the second pass.  I have decided to let such branches produce
  code on both passes but they won't be valid and the SAV directive
  will be ignored anyway when any error occurs.
* Added a test for "DS /" to fill the remainder of a page.  I had
  manually tested this before but I waited to add the test case back in
  again once I had more than 256 bytes of machine code so that my test
  data wouldn't have to be so long.
* I added a comment at the end of the code which indicates that 41
  errors are expected from a test run of this source code.
Cleanup DATA statements for opcode tables.

I removed spaces and quotation marks that weren't required from the
DATA statements used for the 6502 instruction and directive tables.
This will save some space in the BASIC code.

I also verified that the opcode table in the Applesoft BASIC code
matches the opcode table that I have in my snap cross assembler.  At
this point, I think the assembler is ready for me to actually try
using it to write, assemble, and run some 6502 code.

Adding HelloWorld sample

HELLO.BAS includes the code for the latest assembler and ends with a
short program which prints "HELLO RETROCHALLENGE 2013!" on the screen.
Remove DATA.BAS

This initial getting started with Applesoft BASIC code was just taking
up space on my floppy so I deleted it to make room for new assembly
samples.
Allow spaces in ASC operand & handle EQUs in pass 2

Initially I thought it would be OK if I always used spaces to indicate
field delimiters, even within the ASC quoted string.  After writing my
Hello World sample, it became obvious that this wasn't going to work so
I added support for spaces to occur within quoted string fields.

A previous change I had made to how EQUs were handled in pass 2
actually broke the listing output to no longer show "=XXXX" for lines
with EQU assigments.  The handleEQU() routine now sets equValue in both
passes.  This provides generateListOutput() with the data it needs to
display the correct text for EQU lines.

I also added a test case for ASC operands with an included space and
updated the user documentation to indicate that spaces are now
supported in the ASC delimited strings.
