Finally update the websites to point to the new urls

Testing Done:
Compiled but I grepped the code to make sure there aren't any side effects. `PURPLE_WEBSITE` is only used for opening the site or in plugin info and `PURPLE_DEVEL_WEBSITE` is disabled in the about box and spammed to the logs from `core.c` to report errors.
