Batch delay doesn't apply to Update tags.xml

[JMM72]

Although a value is set on 'Batch Delay (ms)' on the settings tab, it's not used for queries like the ones used when updating tags.xml. Currently this causes HTTP error 500 on Danbooru after approximately 150 pages.

This happens since Danbooru change its policy regarding the limit for amount of queries per IP.

It would be good if the Batch Delay could be used for 'batch' queries like the updates, via a checkbox or hardcoded.
