v1.3.0

After saying that v1.2.2 was probably the final release, I decided to try a few more optimisations, tidy up the code and make it easier to include / exclude some features when compiling, depending on your needs.

I have included several TAP images in this release for your convenience;

• full - all features included, coming to a total of 585 bytes
• fd00 / c000 / 8000 / 6000 - non-relocatable versions that load to various points in memory, 506 bytes each
• lite - relocatable but with the find routines, 510 bytes (so can't quite fit in to pages $fd and $fe)

This will probably be the last release. Again.
