JSDOC build cleanup (used to generate jsobjs.html)

Replaced _property_ver_list (array of numbers) with _property_ver_list (array
of objects) with a "ver" and (optional) "desc" property. This solves the
enumeration order problem with objects that have both manual and table-based
properties. Object's property tables (arrays of jsSyncPropertySpec) can now
(optionally) contain the property descriptions. For properties defined in this
manner, there will never be another mismatch between ther name/type and
description/version in the jsobjs.html (a problem has re-occurred several
times through the years with nebulous work-arounds).

We still use _property_desc_list arrays for additional (e.g. manually defined)
properties in such objects or just objects that only use one method of
property definition and are not subject to the enumeration order problem.

Fixed numerous typos.

Using more consistent terminology and HTML mark-up.

Some beautification and enhancement of readability, but nothing too major.
