Tim Mayberry 816f3bfb36 Use std::vector::reserve to improve performance of adding properties 
The number of properties per node roughly corresponds to the number of members
of the class the node is representing and should be fairly low.

Use std::vector::reserve to prevent reallocation on insert for most node types,
there are exceptions like Region(~40 properties).

This seems worth it as part(maybe 1/10th of the total time) of saving a Session
is a combination of what occurs in "Create" and "Write" in this test.
