Add buttons to open the web site and IRC.
Tentatively allow Atlas to be launched from the menu.
Add some shutdown functions to support relaunching into Atlas without
having to restart the whole process.
This was SVN commit r7714.
also rename wchar -> utf8 to avoid conflict with <wchar.h> (requires
rebuild of workspace)
(unfortunately copying history fails to "502 bad gateway"; had to delete
old + add new independently)
This was SVN commit r7340.
