editor_return_does_auto_indent= reversed on 0/1 conversion in ini file to false/true

[Felix Miata <mrmazda earthlink net>]

To reproduce:
> From menu, save settings, where ini last saved quite some time ago contained 0s
for false and 1s for true, including:

        editor_return_does_auto_indent=0

Actual behavior:

        editor_return_does_auto_indent=true

Expected behavior:

        editor_return_does_auto_indent=false

This was causing errant copy/paste into mcedit behavior reported here:

Evolution as taught in public schools is, like religion,
        based on faith, not based on science.
