Solar 0.16.0 released

Version 0.16.0 of the simple object library and application repository for PHP5 was released yesterday, mostly because I needed to make a minor schema change to one of the “content” tables. Seems the word “position” is reserved in some databases, and I was using that as a column name; the migration script in this release renames it to “pos”. There are other minor changes to the Solar_Sql class as well (including more documentation :-).
