SIC: QLocale: Remove base argument from conversion to number api

As discussed on list and approved by Lars and Thiago.

Remove the option to use QLocale to convert strings to non-decimal
numbers as they are not localised and the api is available in QString.

   to use or check both.

+    longer take a parameter for base, they will only perform localised base 10
+    conversions. For converting other bases use the QString methods instead.
