R2.7.0: Mouse support and a brand new User's Guide

1351 Mouse support with a recreated Amiga Workbench 1.3 mouse pointer. And a new User's Guide as a Teletext Service, how cool is that!

Meatloaf users: use the short code, no local software needed, just type LOAD "ML:TELETEXT64",8
If you do want your local copy, get: teletext64-mlf.prg

WiC64 users: you can always start Teletext via the WiC Portal. If you do want your local copy, get: teletext64-wic64.prg.

C64 Ultimate, Ultimate 64 and Ultimate II+ users: get the Teletext64U.D64 image.

The Teletext64W.D64 image is intended for WiC64 users that want to run a local instance; the also need to pick a PetsciiProxy target.
