Added support for Windows-125* character sets in CSV import.

Excel still does not export CSV as UTF-8, using the 8-bit system character set instead, so support for these charsets comes in handy.
This also updates the `convertCharacterEncoding()` function to be a bit smarter when choosing its backend.

See merge request !46

Fix default sort ref #110

this adds code to the model for list views and related list views so that if no sort order is manually specified (someone hasn't clicked a column header) then it checks to see if the performance preference for default sorting is turned on and uses the sort order specified for the module. ref issue #110

if the preference LISTVIEW_DEFAULT_SORTING is specified then use it for list views and related lists
