Display history refactor (#691)
* Create DisplayHistory * Change arguments for _setContentTermsOrKanji * Set up history-driven content updates * Use new history only * Load definitions if missing * Refactor definitions getting * Add support for wildcards * Move definitions setup * Add events * Allow state change even if there is no history state * Update search page to use history * Fix history overwriting * Fix search page not seeing state chang events during prepare * Update state if necessary * Don't reassign query text if the same * Remove DisplayContext * Initialize with real history state * Track URL * Update DisplayHistory to support pseudo-history * Configure history settings on search page * Fix state * Use full URL * Change data format of setContent * Rename details to content * Update event arguments * Fix animation * Remove old state changes * Clear content properly * Remove set/clear content overrides * Fix setting up event listeners for content clear * Make clearContent private * Make focus opt-in * Validate source * Add unloaded type * Generalize content params * Update how extension unload content is assigned * Restore query blurring
