/*
 * BarTab integration - Vimperator Plugin
 *
 * Commands:
 *  :tap          tap the current tab
 *  :tap #        tap the previous seleced tab
 *  :tap {num}:?  tap the {num}-th tab
 *  :tap!         tap all tabs without the current tab
 *
 *    Tab Completion is available !!
 *
 * Completion:
 *  overwrite completion.buffer and urlCompleter
 *  these can search title or url even if the tab is tapped
 *
 *  So, buffer command and urlCompleter ("t" in 'complete' option)
 *  are completable.
 *
 * Other:
 *  overwrite tabs.get method.
