It seems as if the archive was updated at some point in time
without spending a new version number. This commit was needed
after I cleaned all downloads from the meta-ros layer.

Add eigen-conversions as a dependency to image-rotations

Some version updates and minor tuning

some improvements to the speech-tools recipe

Updates till late June 2014

libpoco: use system libraries instead of bundled versions

Poco comes with bundled versions of SQLite3, zlib, expat, etc.
Adding the ``-DPOCO_UNBUNDLED=On`` option to CMake makes it use the ones provided by OE.

The patch provided upstream is part of 1.0.7 and hence is removed.

Updating genlisp to 0.4.14 needs adjusting of the LIC_FILES_CHKSUM
lines.

Updating rosserial to 0.5.6 needs adjusting of the
LIC_FILES_CHKSUM lines.

ros_realtime_tests: updating to 0.1.0

more updates and some minor improvements

The previously applied patch has been included in 1.11.8 and is
removed from the recipe and this repository. Furthermore, the
LIC_FILES_CHKSUMs are adjusted to changes in the package.xml files.
