jappixmini: move modified BOSH proxy out of Jappix source tree to be able to use vanilla Jappix.

This is possible because bosh.php is under MIT license.

Jappix Mini (AGPL license) is not distributed with this addon. You need to
install it manually:
* Download latest zip file named friendica-addon-* from
https://github.com/Leberwurscht/jappix/tags and place the zip file in the
addon folder. Make sure to name it 'jappix.zip' - the download link required
by the AGPL points there.
* Unpack the zip file, rename the folder to 'jappix'. Do not delete jappix.zip.
* Download latest jappix version from https://github.com/jappix/jappix/tags to
addon/jappixmini/jappix.zip. Really make sure you name it 'jappix.zip' - the
download link required by the AGPL points there.
* Unpack the zip file to addon/jappixmini/jappix/. Do not delete jappix.zip.
* Delete the file addon/jappixmini/jappix/index.php. This is important, because
otherwise the installer of Jappix would be publicly accessible.
