GSocket:

- Added lots of comments to both code and headers.
- Restructured some parts of Unix version. Will try to merge with MSW soon
    and have a gsockcmn.c
- Fixed a potential bug in the MSW version of GSocket_Connect when in blocking mode.
- Fixed a potential (different) bug in the corresponding Unix version.
- Now WaitConnection correctly fills out the peer address field.
- Added GAddress_INET_SetAnyAddress (sets address to INADDR_ANY)
- Default address is INADDR_ANY again, not INADDR_NONE; failed hostname lookups
    sets the address to INADDR_NONE.

wxSocket:
- Added some safety checks to the wxPostEvent stuff.

wxIPV4address:
- Added a wxIPV4address::AnyAddress method.

wxIPCConnection and co.:
- Servers bind to INADDR_ANY, instead of binding to localhost.
