Version 3.06.30 of Small HTTP server and Android VPN client

[Maxim Feoktistov]

Version 3.06.30 of Small HTTP server has been created.

   + Added support for reconnecting to VPN.
   + Added share MTU value for VPN client.
   - Fixed web-administration for Linux versions that build with selected security library.

Also an Android version of the VPN client for this server has been created.
  This version is now available for closed testing in Google Play Market only for subscribers of this Google group
     If you want to test an Android application, join the group.
     Limitations:
     Currently the Android VPN client works with a server using GnuTLS (this is the only way for now).
     Currently, the Android VPN client accepts any remote certificates, which does not provide a 100% guarantee of data secrecy.
