House Keeping: Text Control focusGained functions are poorly named

Being in a hurry I kept the original Java function names for focus gain instead
of renaming them to HTML on* style name.

Example:
TextFieldFromDistance_focusGained();
should have become
onFromDistancefocusGained()

Example from SELECT controls I more properly renamed the action function to HTML style
JAVA ChoiceModel_itemStateChanged()
JS function onModelSelect( )
