Updates to Crosstabs
Adjustments to Splitter scaling on window resize
Changed how radio buttons are mapped to options

Radio buttons are now mapped by index, rather than by name. The index
of a radio button is determined by first sorting them by objectName(),
and then assigning them 0 … n
It is recommended that names be prefixed with _1, _2, _3, etc. to
determine their sort order and hence their index.
Updates to BoundComboBox and SEM analysis
Updated Tabs, added Options

SEM is now enabled in settings
Fix to TabBar background
A fix to the AvailableFields list behaviour
Added Repeated Measures to the ANOVA UI

Possibly only temporary, may make this a separate analysis.
Prevent the < and the .001 from being separated

A non-breaking space means they remain on the same line
Variable type system overhaul

Added a new variable type NominalText. Variable types are no longer
enforced in analysis dialogs. Our variable system is now practically
the same as SPSS
