* Disabled the alerts on memory corruption and errors like double free() in the memory allocator.
* When resizing a page, incl. the updates while loading, it now frees the old one before allocating the new one. Should make it usable on Amigas with only 128 MB RAM again for a lot of pages.
* Added download and upload support (Andrea Palmate).
* Changed the memory allocator to support multiple threads for the new download threads.
* Added progress windows for the downloads.
