#477
## Description of change
Add a new option for scaling the overlay.
Gitadora Arena will receive 250% by default.
Various overlay windows have been updated to scale properly, not perfect
but they are at least usable.

n/a, user reported
## Description of change
When copying text to clipboard, the last character was being dropped due
to incorrect string buffer size calculation.
Also, clean up callers to just pass std:string by reference instead of
going back and forth between C-style strings.
Lastly, fix `git archive` in `build_all.sh` which broke after github
migration.
## Compiling
Yes
## Testing
Tested all three callers - IIDX cam hook, scard reader in Cards tab, and
patch manager datecode.
