Added "-rompath" startup option to allow specifying an alternate path for microcode ROMs. Updated raw Ethernet handling to work with ncap (which replaces WinPcap since it's no longer being updated) running in WinPcap mode. Fixed bug with DebuggerPrompt -- when run with stdin/out redirected, Console.Width is 0, resulting in a div/zero issue.

Initial commit of changes for 1.2.3. This includes:
...
- Scripting support: Allows for recording and playback of mouse/keyboard input and various system control actions. Simple (i.e. basic) scripting format.
- Fix for stale packets left in ethernet input queue; packets received by pcap while Alto's receiver is off are discarded.
- Mouse input made more accurate, and tweaked to avoid Alto microcode bug that causes erroneous mouse inputs under very rare circumstances on real hardware, but much more frequently under emulation.
- Small code cleanup here and there. Moved many UI strings to resources, many more to go.

Initial implementation of Trident controller and drives (supporting T-80 and T-300 packs). TFU works and can certify, erase, exercise and manipulate files on Trident packs. TriEx doesn't quite work properly yet. Still some issues to iron out.
...
Added file-backed disk image implementation for use with Trident disk images, did some basic refactoring of disk load/unload logic, added support for creating new (empty) disk images for both Trident and Diablo disks.
Added UI for loading/unloading/creating up to 8 trident packs; added blank Diablo pack creation UI. (Both Windows and *nix interfaces.)
Added configuration support for same (both Windows and *nix.)
Small correction to Print output path browsing logic.
Fixed Windows installer, now places the right ROMs for Alto I configurations in the right place.
Fixed issue when starting up with corrupted configuration. Corrupted configuration is ignored and ContrAlto will run with default config.

Fix for Ethernet bug introduced with switch to SharpPcap: Filtering of packets sent by ourselves doesn't actually take place. Amazingly this didn't break much, but Trek was affected and we can't have that.

- Fixed two memory state machine issues:
...
1) The Orbit microcode occasionally expects to be able to do a double-word read in cycles 6 and 7 instead of the usual 5 and 6.
2) The double-word logic incorrectly handles several species of overlapped read/writes, which Spruce's layout microcode uses.
As a result, Spruce now works, as do the Smalltalk-80 images.
Several tweaks to microcode disassembly (still rough).
Completed Orbit / Dover ROS / Dover Print Engine emulation. Still some rough edges; it works and can create PDF output.
Tweaked Disk Controller's Restore operation, it is now more accurate though wasn't causing any noticable issues.

Switched from PCap.net to SharpPcap for ethernet encapsulation; SharpPcap is cross-platform, this allows raw ethernet encapsulation to work on Linux and OS X.

New hardware implementation:
...
- Orbit controller: implemented and passes ROS-less diagnostics
- ROS: In progress, not functional
- DAC: For Ted Kaehler's Smalltalk Music system (FM and Sampling). Works, generates audio and can capture to WAV file.
- Organ keybard: Stub, enough implemented to make the music system happy (so it will play back music and not crash.)
Some minor cleanup.
New dependency on NAudio package for DAC playback. Installer updated to include NAudio lib.

Fixed disk controller logic (really disk timing logic) so that disk can run at 100% speed (rather than 50% speed). Changed endian-ness for ethernet packet words to match 3mbit bridge. (Similar changes also made to IFS). Removed some dead code.
