Checked the format of the image ID and enable the next button if the image ID format is valid
Added i18n tranlate attribute to the error message
Check if the image ID exists, if not, disable the next button immediately
Adding the missing flag for checking the image existence on the launch config wizard
changed filter label to "Filter" for clarity, changed select and next buttons to tiny round in step 1 of launch instance and launch config wizards for consistency with other subtask buttons, changed next button to tiny round for shape consistency with other next buttons within wizard and also to create size parity with other buttons on that panel
