ZEsarUX changelog:
Added ZEsarUX Network Gaming protocol (ZENG), which allows you to play to any emulated game, using two ZEsarUX instances,
located each one on any part of the world or in a local network. Games doesn't have to be modified, you can use any existing game

Added Pentagon 16C colour mode emulation
Added 1024 KB RAM emulation for Spectrum & Pentagon
Added support for .scl files: can be converted from file selector menu pressing space
Added SNA saving support
Added PZX tape file support
Added ZX81 online game browser
Added Spectrum online game browser
Added total run time statistics
Added checking for updates
Added sending anonymous statistics use
Added setting --disablemenuandexit: it closes the emulator when the menu is going to be opened.
It's the same behaviour as previous --disablemenu. Now --disablemenu only disables the menu but does not close the emulator

Added Borland Gui Style

Added ZRCP commands:
-cpu-code-coverage: working with code coverage
-cpu-history: working with cpu history
-get-ui-io-ports: to get keyboard state and joystick
-get-snapshot: get a ZSF snapshot from ZRCP
-print-footer: print message on footer
-put-snapshot: put a ZSF snapshot from ZRCP
-send-keys-event: simulates key press/release
-set-ui-io-ports: to change keyboard state and joystick
-write-port: write value to a port

Added internal zip decompressor: no more need to use external unzip program
Added setting to reset configuration file to default values

Improved Debugging:
-added setting to dump .zsf snapshot when a cpu panic is fired
-debug CPU window: can now resize height and have more debug lines

Fixed very-old bug when loading Rocman game. This bug existed even on ZXSpectr. It fixes return flags when using tape traps.
Rocman loading screen was shown wrong (having the "any flag loading setting" disabled), but loaded. Enabling that setting crashed the game

Improved breakpoint parser:
-full expression parser: parenthesis, functions, sums, multiplications, etc. Can be used as a full calculator!
-now it's a lot more faster. Up to 7 times faster, so it uses 7 times less cpu than the old version

-fallback (transparency) colour is now a 9-bit value
