Eeschema pin table number sorts on character instead of number

[Stefan Hamminga]

Sort order when clicking the column header in the Eeschema 'Pin table' sorts the pin numbers as:

1
10
100
101
102
...
11
110
111
112
...
etc

This is of course not as useful as a 'natural' numerical sort and certainly against expectations.
