[SrRapero720]

changes:

• make more accessible GuiCounter's controls
• add an contructor with a ControlFormatting argument to use it on +/- buttons (normal and decimal)

this time i finish all the changes, but 100% sure

changes are:

• added custom events for slider and textfield (so less casting and avoid check if x == y.
• stripped out whole ValueParsers feature into individual-primitive parsers
• added some constructors and methods variants to enhance in-line api usage
• make GuiButtonIcon and GuiStateButtonIcon extends GuiIcon (reducing duplicated code)
• added square param on GuiIcon which forces icon rendering to be squared even if button wasn't squared (disabled by default)
• some "let me customize" changes over GuiCounterDecimal
