Several errors fixed having to do with editing the gloss items from the gloss tab or single line edit tab.
Code clean-up
Fixed a bug that was updating the concordance incorrectly when a new text form was added.
Removed the "Link to other interpretation" feature, which was incompatible with the way the data structures have worked out.
Removed "Copy from baseline" for text forms.
Remove a gloss item -- not yet working, this is just a commit before I check out an earlier branch.
Remove gloss items from the gloss tab. (Does not remove phrases yet.)
"Open Line with context..." feature.
Reports an error instead of crashing if an "Open text line" command requests an out-of-bounds value.
Right clicking on a text name in search results no longer produces a drop-down menu.
Fixed a bug in the interlinear text display.
Commented some debug code. Difficult to debug the concordance without having a replicable failure.
