Camera: remove fine/normal/superfine jpegquality and use always int

We use now a set of int values the user can exactly assign. Showing as
well the normal fine superfine as choice is just a duplicate. As well
we can get rid of the weird converts of the mixed values.

To take care that the user does not get into problems we updated the db
version and we make a convertion.

Camera: Fix removal of histogram setting

Histogram is disabled by default in config.xml, so the code to filter unsupported modes is never executed
Remove histogram option completely when it's disabled in config.xml
