define a global page for shared content
make nib table global
autoclear filters instead of case-by-case
cache IDs in global variables where useful
merge some near-duplicated routines
optimise sector reordering
allow cancel when writing from RAM
pack universal RWTS dynamically to allow easier modification
consolidate output when modifying sequential nibble table entries
make Standard Delivery accept a parameter to specify table
switch unpacker to Exomizer for cross-platform support
make relbase dynamic for easier building
makefile for windows

to create the compressed universalrwts.a:
1. acme --cpu 6502 --setpc 0 -o universalrwts.bin universalrwts.org
2. appack c universalrwts.bin universalrwts.pak
3. use a sector editor to remove the first #$18 bytes of the universalrwts.pak file
4. convert the binary back to ACME-compatible text (!byte, '$' for hex, no trailing commas)
5. save in universalrwts.a
