QML activity interacts with backend.

Test QML activity changed for a simplified version of drbob's rsqml-models.
It requests JSON documents from the libresapilocalserver and shows them raw.
Updated Android documentation.
Moved Android qmake section to the end of libretroshare.pro and openpgpsdk.pro
to avoid static linking errors.
