maint-bin: Make all options configurable; no more spammy git commits. :)

All the tools now look in maint-bin/maint-settings.ini for config settings.
So now when I (or anyone else) wishes to change the tool behaviour,
they don't need to commit new code.  This should result in less
commit spam.

A sample settings file is included with this commit.
