Added Unirom Memory Card support

• Added support for Unirom Memory Card reading/writing via serial and TCP (Thanks Spicyjpeg).
• Fixed issue with detecting Atmega328P boards with MemCARDuino (Thanks Carmax91).

Support for .VMC, Vita "MCX", better support for RAW files

• Bumped up .NET requirements to 4.8.
• 115200 bps is now default speed for supported hardware with legacy 38400 bps available in preferences.
• Removed glass support as it's not needed for modern Windows and it seems to be causing problems with Mono.
• Added support for Arduino Leonardo/Micro for MemCARDuino.
• RAW files can now be exported using it's own dialog to not mess up the file name.
  • Also it will produce a text file with a proper name if there are unsupported characters found.
• Added TCP option for PS1CardLink (Thanks to Imiori92).
• Added support for .vmc file extension used by POPSstarter.
• Added support for Vita "MCX" used by Vita's PocketStation Emulator (Thanks to KuromeSan).
• More MONO fixes by bitrot-alpha.

Full VMP and PSV support

Thanks to @robxnano MemcardRex now features full support for the signed VMP and PSV save formats.
A bug that created headless new memory cards is now fixed.
MMX4 single save can now be imported normally (save contains lowercase magic).

PS3 MC Adaptor support

Thanks to @ndepoel MemcardRex now features PS3 Memory Card Adaptor support.
Tested and works with FreePSXBoot :)

This package contains everything needed in a single archive. Plugins have also been updated to .NET 4.5.

FreePSXBoot fix

This release disables a feature to auto correct corrupted Memory Cards because FreePSXBoot breaks if it's enabled.
The option is now user configurable in the preferences window and is off by default.

FreePSXBoot should work out of the box from now on :)
