Merge of r4828: "include" with wildcards in map and types blocks.

Merge of r4828: "include" with wildcards in map and types blocks.

The "include" directive should be able to include multiple files if
given a filename mask.  Fixed this to work for "include" directives
inside the "map" or "types" blocks.  The "include" directive inside
the "geo" block is still not fixed.
