LP#1694577 Report templates search API & paging

Adds new API call open-ils.reporter.search.templates allowing search of
reporter template names and/or descriptions.  Searching is
case-insensitive, any order, with left-anchored words.  Searching can be
for specific folders or all folders visible to the calling user.

Adds paging support (limit / offset) for retriving templates, reports,
and outputs.
