minibar: refactoring for improved modularity

Browse Source 
Two smaller objects have been factored out from the Minibar object:
Input and Translations. These have been placed in two separate files:
minibar_input.js and minibar_translations.js. Some common auxiliary functions
have also been moved to a separate file: minibar_support.js
