config.sitemanage.moreInfoDir property default will not work

The SAK-16600 issue introduced new functionality, including the ability to specify a "more info" link for tools, which will load images in the config.sitemanage.moreInfoDir directory.

The directory location requires that there be no leading slash ("/" as in "library/images/"), or the location will not correctly resolve, so the specified default does not work.

Suggest changing the code to allow/require a leading slash since this specifies a relative URL. Support for specifying a web location (e.g. https://someserver/library/images/ would be really nice, but this is an enhancement.
