[noace] fix sub-second time reporting by Time::now without ACE

Thanks @lschilli, fixes #154
ControlBoardWrapper: Fix typo in error message
Import GtkDatabox 0.9.2 in external

Remove msvc.patch applied upstream and update CMake build system
Require GtkDatabox 0.9.2

Using a "2 rows - 1 column plot" in yarpscope with previous version, the
size of the ygrid in plot1 is used also in plot2, regardless of the xml
configuration params.
[bindings] use python libraries for default interpreter, see #151
[bindings] simplify python logic, rename var to YARP_USE_PYTHON_VERSION

Thanks @drdanz.  Fixes #151.  The libraries found by FindPythonLibs
are somewhat haphazard in older CMake versions.  This commit makes
them more predictable and more likely to default to what you want
(libraries that work with your default python interpreter).

I'm not sure why I disabled it in the first place

YARP_manager library installation does no longer require CMake 2.8.10
Set YARP_EXPERIMENTAL_MANAGER_LIBRARY=TRUE in experimental builds
Rename libraries created in external folder using prefix "YARP_priv_"

Update YarpDescribe to filter out YARP_priv libraries from the
YARP_LIBRARIES variable.

Also install tinyxml, if YARP_EXPERIMENTAL_MANAGER_LIB is enabled.
This is required because YARP_manager requires that target that is not
in the export list.
Add imageRegistrationMode option
Add syncFrames option
Remove support for calling add_library() instead of yarp_add_plugin()
