forked from I2P_Developers/i2p.i2p
oOo's patch to add support for temporary name<-->destination assignment (w00t!)
to use this, make a link going to http://some.name.i2p/some/path/blah?i2paddresshelper=base64Destination e.g. http://whitehouse.gov.i2p/?i2paddresshelper=FpCkYW5pwVz36sSHoBuRT4ZvGif9QC9oQUWfz-wu4zEnJ1ewlAvinPuw3YnXUKmgLFZ0UY3wB7wqd0eQYiW2ZV1bwVhXvsyGV5ZehzxGaFu05IspCJjyaMIe90z5fyda4KgzyBwHKqwjGX57SMyn2cZhXbCKF6aNuipWxYOnL65uATDbw3jShEtL9v9299ohhGA3EcrYk3u86FgLmsOdi2GZruxy2RzioA-VKhaZl4RSJs6dFHPUYWgeLF3gT7Ciy-HbMZdDuiLTEX7mUlO0UZwnzT8mjUDeeYfyWtv9arwv-rAMeXxAVUYm7X2dDHN8TvmQCZ~LiQrnGmGReSIDKVT4u59xZX2Qg0GZf0fA5LRSW1zHLrlZWDJfNeESW57RlOkA9DDDOxwSVSw8LUQN-hPsoz~AgwA-vDklNWULqvp4lLifEJUlr5ZmnWrviLr6W6cHhdJBl89VzMThoknb5UibIvwTnu~tfA0rkyILXX07hdaoXF~prptuOhMtEcV2AAAA this is better than the existing http://i2p/base64Destination/ since images at that page will now resolve the name is resolved only if/when the hosts.txt doesn't have a matching entry (aka no spoofing duck.i2p), but the name is *not* persisted to hosts.txt - if you restart your tunnel (or router, if they're in the same JVM), the address helper is lost
