Change more filenames to strings.
Remove old commented code.
Change some class IDs to strings.
Change some exceptions to use strings.

This code doesn't seem to be compiled though.
The HASH find function's parameter should be const.
Change Data Items and Tags to use strings.
Change STDdstream to use a string.
Change NetStream to use strings.
Replace STDbool with regular bools.
Replace STDmem_queue with a stringbuf.
Remove mem_push files.

These files define the mem_push and STDmem_* classes. However, they just
re-implement stuff in STL and all usage has been replaced.
Fix extra elements in renderer lists.

With a vector, specifying a size pre-allocates that many elements, but
pushing to the back adds on to the end. The previous ARRAY thing just
used the size as an initial allocation, without specifying that there
were any elements there.
