removed dependency from hector_common as hector_marker_drawing has been moved to hector_slam stack
Merge remote-tracking branch 'origin/master'
hector_worldmodel_geotiff_plugins: new include file locations in package hector_geotiff
hector_worldmodel: renamed package worldmodel_msgs to hector_worldmodel_msgs
hector_object_tracker: renamed hector_object_tracker::param() method to hector_object_tracker::parameter()

This will hopefully fix the build failures on Jenkins for lucid binaries.

hector_worldmodel: bumped version to 0.2.2
