Installer bug fix release

This is a minor update of R1002, which fixes a long-standing but not discovered bug when restoring data in flash while running the installer (see issue #24 )

Installing

The easiest way to update an existing Spectranet to the latest release is to:

mount 0, "vexed4.alioth.net"
%load ""

Then choose option A, firmware check/update.

To install manually from a download, most users will want installer.tap (or installer.tzx as preference dictates). The general procedure is:

CLEAR 26999
LOAD "" CODE             (now play the TAP or TZX file in through the tape port, or use a DivIDE)
RANDOMIZE USR 27000

The baseinst.tap/tzx file installs just the base ROMs (and no modules). The insconfig.tap/tzx installs and runs a configure step for new hardware that's never been configured.

ROM compatibility update and desertkun's trap handling

Now supports newer flash chips with 4K sectors for the issue 3 PCB

Now supports C style debugging of programs on real hardware, see commit b6dfa48
