readme: mention unit tests directory
readme: also mention the shared directory.
Branding: Rename application to taulabs
Branding: Replace remaining instances of "Above Ground Labs" with "Tau Labs"
Windows Packaging
OSX Packaging
Packaging: Update android
gtest: stop compiling gtest libraries on installation
unittest: build gtest-all and gtest_main directly
Raspberry PI build: Add a flag to exclude some of the plugins

For things like Raspberry PI we need to remove some of the more
memory intensive plugins or ones that require OpenGL (pending
Qt5).  To compile with this reduced set use this command:

make GCS_QMAKE_OPTS="CONFIG+=LIGHTWEIGHT_GCS" -j7 gcs
Rasbperry PI build: Add scope to the list of excluded builds
Linux packaging
Fix some typos
Fix: Tau labs
Packaging: a package_matlab target

Previously the way matlab was being packaged it was required for
packaging but wasn't actually done before the scripts which make
the platform specific bundles was run.  The code still should be
refactored so that there is a clear set of things built, then the
packaging step.  However, this fixes it for now.

Also make sure the matlab packaging depends on uavobjects
Logo: Check in a new logo.  This is mostly a placeholder.

Also update the references from abovegroundlabs to taulabs.
When replacing the logo again only replace the .icns .ico
and .png files.
Rename .pri files from abovegroundlabs to taulabs
GCS: Remove outputpane.h.  This doesn't seem to be used for anything.

Triggers compilation errors on windows.
Pluginspec files: Update from abovegroundlabs to taulabs
OSX Packaging: Update packaging script.

macdeployqt seems to have been improved since Qt 4.8.0 so
now copying in all the missing Qt libraries is no longer
required.  This removes the uneeded code and suppress a
bunch of warnings.
