Gnuplot version 5.4.5 release

This release fixes a regression affecting 5.4.4 (only) that caused
string->integer
type promotion to incorrectly interpret leading '0' characters as indicating an
octal number.  For example in extracting sequence numbers from file names
run_001.dat through run_010.data would fail on run_009.dat ('9' is not a legal
octal character) and file_010.dat would yield 8 rather than 10.

This release also fixes mousing the Windows qt terminal during a "pause"
command.

There are two new features back-ported from 5.5;  both are illustrated
in this plot from the development version demo collection.
