Add IGUISpinBox functions getValueFor and getOldValue

Browse Source 
Also documenting some missing feature (decimal places ignored with direct text input)
getValueFor allows to check the value a given text would have 
getOldValue can be used to check the previous value in a EGET_SPINBOX_CHANGED event
