Low: ui_configure: Fix error in __conf_object
Low: main: Fix issues with ctrl+C and profiling
Low: bash_completion: Improve colon-handling

This updated version of the bash completion uses some
methods adapted from the bash_completion package to
handle colon-separated words somewhat better. Still can't
handle words separated by more than one colon
(so ocf:heartbeat:Dummy still doesn't complete correctly).
Low: main.compgen: Adapt output to bash completion
Low: ui_ra: Updated completion for info
