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.

- 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.

General code cleanup. Fixed debugger display of RAM banks for 3K systems, cleaned up logic for displaying ucode memory. Implemented memory timing for Alto I systems, incorporated Alto I uCode ROMs from Al K, which now boot. ST-74 runs better now.

Ethernet! A really hacky version of Ethernet. Can play MazeWar, but still needs work.
