SPC700 additions.

* First completed version of SPC700.  Very untested.

* Fixed an oddity in the parser regarding quoted values not ending with a
  separator.  These values now appear unquoted with the additional text included
  in the same argument.

+<h2>Using the SPC700</h2>
+
+The SPC700 processor can be selected by passing <b>spc700</b> to the processor
+directive, i.e.
+
+<pre class="codeblock">
+        processor spc700
+</pre>
+
+<h2>Opcodes</h2>
+
+I could find no official documentation on The SPC700, so the assembler uses what
+seems to be the accepted opcode format.
+
+
+<h2>Options</h2>
+
+The SPC700 assembler has the following options.

+<td class="head">Description</td></tr></thead>
