Copied the extension script tutorial files out of the Scripts
directory and into the Tutorial directory. This makes more sense,
and makes it possible to expand the script sample without altering
the tutorial.
Reverted the Scripts sample to be an actual sample, rather than a
tutorial.
Renumbered the last two tutorials and added them to the ToC. This
gives them actual numbers rather than treating them as add-ons to
the advanced tutorial.
Moved the source files for the tutorial binaries into a subdirectory
to reduce clutter.
This does mean we have two separate copies of the inline string
sample plugins, but that's an artifact of our attempts at security.
Sort of silly to have every handler immediately pull the operand out
of the file data. (This is arguably less efficient, since we now
have to serialize the argument across the AppDomain boundary, but
we should be okay spending a few extra nanoseconds here.)
We were failing to update properly when a label changed if the label
was one that a plugin cared about. The problem is that a label
add/remove operation skips the code analysis, and a label edit skips
everything but the display update. Plugins only run during the code
analysis pass, so changes weren't being reflected in the display
list until something caused it to refresh.
The solution is to ask the plugin if the label being changed is one
that it cares about. This allows the plugin to use the same
wildcard-match logic that it uses elsewhere.
For efficiency, and to reduce clutter in plugins that don't care
about symbols, a new interface class has been created to handle the
"here are the symbols" call and the "do you care about this label"
call.
The program in Examples/Scripts has been updated to show a very
simple single-call plugin and a slightly more complex multi-call
plugin.
Also, updated LZ4FH sample, which needed to have explicit widths on
a couple of zero-page pointers.
Also, updated Zippy sample, which had a ton of unnecessary format
entries for a couple of pointers.
I was using the plain names, but when you've got symbols like
READ and WAIT it's too easy to have a conflict and it's not plainly
obvious where something came from. Now all monitor symbols begin
with MON_, and Applesoft symbols begin with BAS_.
The Amper-fdraw example ended up with a few broken symbol refs,
because it was created before project/platform symbols followed the
"nearby" rules, and was explicitly naming LINNUM and AMPERV. I
switched the operands to default, and they now auto-format correctly.
I added a few more entries to Applesoft while I was at it.
