MartyPC 0.4.1

This is mostly a bugfix release, although there is one new feature: the V20's 8080 emulation mode is now supported. This hasn't been as rigorously tested as I'd like, so please report any issues you may encounter.

Frontend Bug Fixes / Improvements

• Added 'custom' ROM feature flag to make it easier to load custom ROM extensions.
• Removed bad IBM ROM definition file
• Added 'repeat' field to ROM definitions and changed IBM ROM definitions to use it - fixes 1982 5160 BIOSes
• Fixed CPU Status window updating when paused/stepping
• Fixed PIQ flush on V20 CPU
• Added Mode flag to CPU Status Window when using a V20 CPU
• Fixed --machinescan option
• Improved unique filename generation function - avoids O(n) behavior as file list grows (now O(log N), O(1) with hint)

Core Bug Fixes / Improvements

• Preliminary support for the V20's 8080 emulation mode
• Fixed VGA cursor disable bit (Ferraro reference had it backwards)
• Fixed controller support on Windows 7
• Added additional hard disk geometries to Xebec controller
