Ignore more build artefacts.
common: add roslaunch testing.

In preparation of repository refactoring: roslaunch tests will be
used to perform regression testing to make sure all changes remain
backward compatible (wrt executable artefacts, resources and launch
files).
driver: move driver (Rapid and nodes) into separate package.

Node sources, headers and launch files copied from abb_common.
driver: remove default for J23 coupling parameter.

Users should explicitly provide this on the command line, or use one
of the convenience launchfiles provided with the support packages.

It is of critical importance that this parameter is set to the
correct value, and should therefore not be supplied a default in
a (for end-users) file with low visibility.
irb6600: move IRB 6600 support into separate support pkg.

Meshes and urdfs copied from abb_common package.
irb2400: move IRB 2400 support into separate support pkg.

Meshes and urdfs copied from abb_common package.
irb5400: move IRB 5400 support into separate support pkg.

Meshes and urdfs copied from abb_common package.
meta: add new IRB support packages (2400, 5400 & 6600).
support: add robot interface and visualisation convenience launchfiles.

Defaults for 'J23_coupled' argument/parameter copied from irb_2400_moveit_config
and irb_6640_moveit_config packages.

TODO: provide default for coupling factor of IRB 5400 (no existing value available).
support: add roslaunch testing.
irb2400: add basic (regenerated) MoveIt package.

Regenerated package, updated version of the irb_2400_moveit_config.

This uses the files from the abb_irb2400_support package.

Note: acceleration limits are identical to those specified in the
old irb_2400_moveit_config package (ie: 1.0 m/s^2), which should
be updated to more realistic values.
irb2400: (re)add plan execution support to MoveIt package.
irb6640: add basic (regenerated) MoveIt package.

Regenerated package, updated version of the irb_6640_moveit_config.

This uses the files from the abb_irb6600_support package.
irb6640: (re)add plan execution support to MoveIt package.
irb2400: add regenerated IKFast Moveit plugin.
irb2400: update MoveIt config to use IKFast plugin.
meta: add IRB 2400 & 6640 MoveIt configs and plugin pkgs.
Add deprecation notice to old packages.

And point users to the replacements.
Bump versions.
driver: reintroduce coupling factor default.
