Altered the address region edit UI a little to improve clarity.
Also, close the hex dump viewer window when Escape is hit. (The
tool windows don't have "cancel" buttons, so the key has to be
handled explicitly.)
Added a pop-up menu with three options: default (curly quotes),
straight, and Merlin. Removed the "reset to defaults" buttons.
Also, slightly rearranged the Display Format tab so that the quick
set pop-up is on the left, near the items it affects. Moved the
"use comma-separated format for bulk data" checkbox over as well,
since it's part of the set.
This allows regions that hold variable storage to be marked as data
that is initialized by the program before it is used. Previously
the choices were to treat it as bulk data (initialized) or junk
(totally unused), neither of which are correct.
This is functionally equivalent to "junk" as far as source code
generation is concerned (though it doesn't have to be).
For the code/data/junk counter, uninitialized data is counted as
junk, because it technically does not need to be part of the binary.
This action removes operand formatting from all code and data in the
selected range. In most cases this is equivalent to simply editing
the various items and clicking the "default" format radio button,
but the feature can be used to remove data formats that end up inside
multi-byte instructions. Instructions with such formats cause warnings
and were tricky to fix.
Labels embedded in multi-byte items are also tricky to remove, so this
clears those as well. It does not remove visible labels. This is
done in a single pass, which means that labels that would become visible
after the formatting is cleared will still be removed.
Also, fix inclusion of address range end lines when restoring the
selection. Their peculiar nature -- being associated with the offset
of the last byte of multi-byte items -- was interfering with the
selection save code. This does not add them to the selection when
an address region deletion is undone, since technically they weren't
part of the selection.
Also, moved Edit Note higher in the Actions menu.
Added a warning to the index page that only appears when viewing it
over http/https. The issue is that the manual on the web reflects the
tip-of-tree sources, which may be inaccurate for whatever version the
user has.
Also, provide an alternate path to opening the manual in-app when
under development.
Move the SourceGen manual to a subdirectory in "docs", so that it can
be accessed directly from the 6502bench web site. The place where
it's installed in the distribution doesn't change.
