Fix 2013-12-08 "Binky" compatibilty issue (un-saveable config)

All onoff configuration switches do not get saved when the user changes
the value. The reason was that I used true|false for "onoff" switches
although only 1|0 was allowed [1] (never noticed this).

It worked for years but the way the configuration gets parsed by DokuWiki
was changed [2] [3] after Binky RC2, so the bug affects the current
DokuWiki Binky final only.
