Update ServalD for byte[] output list
MeshMS do not use temp file to extract manifest

Refactor ServalD and ServalDResult to store output fields as byte[] instead of
String.  New RhizomeExtractManifestResult.manifest field to contain
RhizomeManifest object of directly extracted manifest.
Upgrade to latest servald (branch 'whacktmps')
Rename BUILD.txt to build.sh, improve comments and tests

Ensure outgoing ACK is added to a message log sent from ourselves. Fixes #49
Better handling of MeshMS with multiple identities
First draft of Sensor Logging demo instructions
Reorganise INSTALL.md

Requirements for each step instead of globally, making easier for other
documents to refer to individual steps.
Fix remaining sloppy uses of File.createTempFile()

New Rhizome "tmp" directory, which gets cleaned on startup, used for
RhizomeProvider files and also for responding to rhizome share-file intents and
sharing files.

Introduce new basic ServalD interface class, FileHash, and use it everywhere
instead of String (cleans up one TODO comment).
Update Sensor Logger demo instructions

Simplify considerably by removing need for Android SDK (adb).  Use QR codes for
direct download to the Android devices.  Download a Batphone APK pre-configured
to connect to Serval HQ, so no need for manual configuration.
