- added _RDUMP to required library
- added MSWAP to common library
- deleted full required library from each disk except #2, replaced with min versions (still need to update demos accordingly)
- added beginnings of error handling in required library
- 16bit array subroutines will be added here at a later date.
- Strings library separated from arrays on its own disk in anticipation of larger libraries.
As it turns out, I'm already running out of disk space with two libraries on the core disk, leaving about 50 sectors leeway for future growth. So I've had to rethink the disk management.
