making this guy a better citizen

[plentz]

these methods need to become private and not extenal:
unmaskMoney
mask
setCursorPosition
getInputSelection

they will become this
.maskMoney('unmask')
.maskMoney('mask')
the other 2 methods will be vanished.

following this guidelines:
http://docs.jquery.com/Plugins/Authoring#Namespacing
http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery#Plug_me:_Writing_your_own_plugins

this will make maskMoney a better citizen(mainly with @digitalBush's jquery.maskedinput)

note: remember to update the docs and examples.
