- set numZoomLevels to 19 to be sufficient for our td1 base map and is what ism should really be set to anyway.
- changed ams layer format to png instead of jpeg since ism also saves png by default. bit easier to know what we are caching and test.
- when caching complete forcing a refresh so that the tiles are pulled.
