g.gui.timeline datasets with the same name

[martinl]

When more datasets with the same name are found in the search path than g.gui.timeline shows appropriate dialog (in contrast with g.gui.animation, see #2273) - see attachment:g-gui-timeline-dialog.png. This dialog doesn't show datasets according to the search path.

g.mapset -p
modis2002lst_yfsg

t.list

huh, trac behaves strangely, it created duplicated tickets when attaching the file, sorry, closing - duplicated with #2275
