TODO FEATURES:

1.1.1 Bugs:
* defaultValue is not set and should be, on initialization, so the reset button works properly; OK!
* Next form element should be visible. (offsetWidth and height > 0);
* âêô are not in the @ rule; OK!
* set the size of the input, as an option. OK!


* allow a default value to be at the input if you try to delete everything; OK!
* a callback should be called when you input something that is incorrect, something is correct and the mask is full; OK!
* make a function that will mask a string just like it does with the inputs; OK!
* allow the setMask function to be used as setMask({mask:"3213",type:"reverse"}) and stuff. OK!
* the value from the input will be masked at the time it's applied; OK!
* allow negative numbers to be written on number masks. OK
* iphone support -- OK, TESTAR NOVAMENTE
* set the signal at the default value, not at a new option. Will be easier to setup and when you need a number with signal you'll always
need a default value, althoug you could have '-' as the input value... it would look weird. OK

* FIX: 'phone-us' mask is now '(999) 999-9999';
* CHANGE: change the 'infinite' mask name to 'repeat'; OK!
* NEW: let 'repeat' have a maxLength; OK!
* NEW: auto-tab focus form element from next form; OK! cool!
* NEW: allow auto-tab, to focus the next form element when the input is completely filled; OK!
* NEW: let the next input to be focused by auto-tab be selectable by a css selector; OK!
* DEPRECATE: deprecated unmaskedVal. This function is too buggy... works for most cases but not all. The best way to do it is by doing it yourself. OK
* FIX: fire the change event on reverse mask; OK
* NEW: let masks have they're own fixedChars option, to give more flexibility; OK
* fix usability bug that prevent correct character from being inputted;
