reuse observer functions for @debounced callback handlers

[georgejecook]

THIS IS BETTER

function m_wireUpObservers()
m.top.observeField("styleKey", "on_styleKey")
m.top.observeField("text", "on_text")
m.top.observeField("size", "on_size")
for each field in ["isDisabled", "showBackground", "textStyle", "focusedTextStyle", "footprintTextStyle", "disabledTextStyle", "backgroundUri", "focusedBackgroundUri", "footprintBackgroundUri", "backgroundColor", "focusedBackgroundColor", "footprintBackgroundColor", "textOffset", "textSize", "backgroundPosterSize", "backgroundPosterOffset", "disabledBackgroundColor", "focusState", "textAlign", "iconStyle", "iconUri"
]
m.top.observeField(field, "on_disabledBackgroundColor")
end for
m.top.observeField("__debugM", "on___debugM")
end function
