Respect Scratchpad RAM

I knew this would eventually need to be fixed.

• c2d's loaders do not overwrite scratchpad RAM, just the splash page data is moved into $400-$7FF.

New:

• Support for TEXT/GR splash screen. See README.md for examples.

-r option to override bar row

e.g.:

c2d -b -r 10 -t barloader.textpage gameserverclient,800 gameserverclientbar.dsk

-b option for animated bar

See barloader.text as an example, e.g.:

c2d -b -t barloader.textpage gameserverclient,800 gameserverclient.dsk

screen hole patching

• added to c2d -t screen automatic text screen hole patching to fix disk stutter from some splash pages, can be disable with -u option.
• granular testing (test, fulltest, emutest)

ok, really done for now

• fixed applescript test script random crash (i hope)

done for now

• added emulator-based testing (Virtual ][ with AppleScript, OSX only)
• more testing
• more optimizations for text2page, page2text
• some code cleanup

more cleanup, moved loader to $300
