[issue17535] IDLE editor line numbers

[Terry J. Reedy]

Tal's 2 issues above have been resolved.
1. Line numbers are initially off by default but this can be reversed on the Settings General tab.
2. Line numbers can be shown and hidden for a window on the Option menu.

The only bug I know of that must be fixed before merging is that font changes do not always get propagated to the numbers.

I recently added 1 pixel of padding to line up line numbers and text.  How is is on other machines?  Especially Mac, if anyone has one?  (Tal's just broke.) Easy test: open a new file; type multiple 2s and 7s on lines 2 and 7.  Eyeball, then, use paper to see if low and high horizontal lines on 2s and 7s are lined up properly.
