all: update manifest links to wiki. Fix #121.
tests: explicitly declare dependencies of roslaunch tests. Fix #70.

This introduces a hard dependency on roslaunch >= v1.9.55, but that
has been released into Groovy, Hydro & Indigo. Package manifests have
been updated to build_depend on that version or newer.

The industrial_robot_client package doesn't prefix its targets, so
any package declaring a 'joint_trajectory_action' target will
satisfy the roslaunch dependency (but also shouldn't build, as it
will clash with industrial_robot_client).
m10ia: import pkgs from experimental repository.
m16ib20: import pkgs from experimental repository.
m20ia: import pkgs from experimental repository.
m430ia: import pkgs from experimental repository.
lrmate200ic: import pkgs from experimental repository. For #103.
Update manifests of imported pkgs with correct URLs.
meta: update run_depends (include imported pkgs).
Ignore mongodb artefacts.
all: sync (and bump) version numbers.
all: fix spelling of ROS-Industrial.
Experiment with KAREL motion interface.

Small test with the (deprecated) KAREL MOVETO and related instructions. By
specifying a SEG_TIME we let the controller approximate ROS-I command
velocity for the current trajectory segment.

TODO: test performance objectively.
TODO: do this with TPE.
