Merge 'ext.templateDataGenerator.ui.images' into 'ext.templateData.images'

Only ever used together as dependencies for module
'ext.templateDataGenerator.editTemplatePage'.
In the UI, they provide icons for the same dialog.

The 'ext.templateData.images' module is also used in one other place,
via addModuleStyles() on NS_TEMPLATE pages that use <templatedata>.

The 'template-format-block' and 'template-format-inline' icons
are used by the Parser output HTML for the documentation block.
Having one unused icon there, preloaded for editing templatedata,
seems acceptable given it's so tiny and basically was already being
paid for on page views with the mere existence of the module taking
up about as much space as the icon itself.
