CLI/Tcl: fix version check (need <= 999 for DAFT permille)

UPNQR: fix required binary mode using mode_preset
UPNQR: allow mask to be manually specified
GUI: use non-native QColorDialog on Unix also; no noEXE for CLI equivalent;
  add shortcuts for copy-to-clipboard and CLI equivalent

        commonly used one-dimensional barcode schemes, pharmacode does not store the data in a
        form corresponding to the human-readable digits; the number is encoded in binary, rather
        than decimal. Pharmacode is read from right to left: with n as the bar position starting
-       at 0 on the right, each narrow bar adds 2n to the value and each wide bar adds 2(2^n).
+       at 0 on the right, each narrow bar adds 2^n to the value and each wide bar adds 2(2^n).
        The minimum barcode is 2 bars and the maximum 16, so the smallest number that could
        be encoded is 3 (2 narrow bars) and the biggest is 131070 (16 wide bars)."
