2 concrete classes which are currently implemented: * BSpinner (works on int32s) * BDecimalSpinner (works on doubles) In addition BAbstractSpinner now inherits from BControl instead of BView/BInvoker. This allowed for code simplification at the cost of needing to cast for the decimal version because SetValue(int32 value) comes from BControl. Also, add a spinner_button_style enum with 3 options: * SPINNER_BUTTON_HORIZONTAL_ARROWS * SPINNER_BUTTON_VERTICAL_ARROWS * SPINNER_BUTTON_PLUS_MINUS which sets the spinner arrows to either use horizontal arrows (left/right) vertical arrows, (up/down), or +/- symbols (the default). If the spinner button is using horizontal arrows you can decrement and increment the spinner value by pushing control+left/right, otherwise you can increment and decrement by pushing up or down. The reason for needing control is so that you can move the cursor in the textbox otherwise. Switch the 3 apps that are currently using BSpinners to use the integer variety in Deskbar preferences, WebPostive preferences, and Screen preferences.
