## Description of change
Saving patches to file used to rewrite the file repeatedly, now it loads
and saves only once. Original file timestamp is now preserved on the
backup.
## Testing
Saved a very large patch set that used to take 10+ seconds; now it is
instant. Confirmed hex diffs are still accurate.

## Description of change
When opening the patches tab by pressing F4 in game, the Save button
doesn't appear until after initially selecting/deselecting a patch, then
it shifts all of the patch text below. To solve this annoyance, this
keeps the Save button in a fixed position (starts greyed out until a
selection) and no longer shifts the text.
## Testing
Confirmed saving selected patches still works properly in the overlay
and standalone cfg

## Description of change
Add `-icmphook` option under spicecfg Development/Network for emulating
keepalive ping replies in user mode, so games do not need to open
privileged raw ICMP sockets. This makes connecting to networks possible
on macOS under Whisky, and on Windows with ICMP firewalled or spice
running without Administrator privileges.
## Testing
Tested DDR and SDVX on Windows 10 and macOS Tahoe. Network check status
in test menu shows `CONNECTED` when -icmphook is enabled, and `NOT
CONNECTED` when it is disabled. Actual network functionality works as
expected (under previously impossible conditions).
