major, substantive reworking of how we store GUI information (visibility, height) for automation data. old design stored (insufficient) identifying information plus actual data in a GUI-only XML node; new scheme adds GUI data via extra_xml node to each AutomationControl object. reworked public/private methods for showing/hiding TimeAxisView objects; changed labelling of automation tracks to just show the name of the controlled parameter - more info can be viewed in the tooltip for the track headers. NOTE: Session file format ALTERED. No data loss but track visibility may be different than previous ardour3 versions
