Revision 955

    Sorry for the massive change, one thing leads to another..
    Updated the login and status pages to be single-page based.  Removed the old
    pages and added the new ones.
    Added a configure option for dmalloc, and header file detection.
    Added documentation for the template related configuration options.
    Added documentation for usage of the templates.
    Cleaned up a bunch of non-free()ed pointers.
    Added a sanity check in libpbc_config_getstring to check for option keys
    suddenly becoming NULL, a good sign of memory corruption.
    Changed the list allocation code to explicitly malloc() on the first time
    through the loop, because realloc() doesn't have to behave right with a NULL
    pointer (although it almost always does.)
