The EtchedPixels floppy disk controller is known by the identifier
'FDMODE_EPFDC', but the comments in the Config subdirectory have an
incorrect reference to 'EPWDC'. This fix updates the comments to use the
correct name.
- Added ability to enable VGARC and front panel in default config without I/O conflicts (does **not** support having both types of hardware present at the same time).
- Fixed documentation error in issue #345 reported by @MorfeoMatrixx.
