Improve default values for folder list page size configuration properties

From PRODDOCS-651:

Clients often have performance issues in the CMS if there are many items within a folder. It's quite easy to mitigate this by changing some properties:
The following locations at the console:
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippostd:folder
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippostd:directory
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippogallery:stdImageGallery
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippogallery:stdAssetGallery
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/urlrewriter:ruleset
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippo:facetsearch
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hipposys:facetsubsearch
/console/?path=/hippo:configuration/hippo:frontend/cms/cms-folder-views/hippo:facetselect
Some of the locations might not be used in every installation, and there might be more?
Recommended changing the following properties:
list.page.size was: 500 -> change to -> 50
list.view.size was: 3 -> change to -> 10

Perhaps instead of letting customers run into this issue, then having to look up documentation and change configuration, we should use better default values?
